St. Patrick’s original color was blue. Not green. Not even close to green. A soft, sky-like blue called “St. Patrick’s Blue” that you can still find on old Irish presidential standards and medieval coats of arms. The green takeover happened centuries later, tied to Irish nationalism, the shamrock, and eventually an entire holiday industrial complex that would have baffled the man himself. I’ve opened trivia nights with that fact and watched tables of people in green wigs look at each other like I’d just told them Santa was from Finland. Which, incidentally, he sort of is.
I’ve been writing and hosting St Patrick’s Day trivia for years, and what I’ve learned is that this holiday sits in a strange sweet spot. Everyone thinks they know the basics. Almost nobody actually does. The confidence people bring to questions about St. Patrick, about Ireland, about the history of this celebration is exactly the kind of confidence that makes for the best trivia moments. The kind where the room goes quiet, then loud.
These 50 questions are built for that. Some will feel easy. Some will start fights. A few will make you pull out your phone to verify, which is the highest compliment a trivia question can receive. Whether you’re hosting a pub quiz, running a party game, or just looking for quality st patrick’s day trivia to lord over your friends, this is the set.
The Man Behind the Myth
1. What modern-day country was St. Patrick actually born in?
Everyone’s first instinct is to say Ireland. That’s the whole point of the question. Patrick is the patron saint of a country he wasn’t from, which is a detail that rewires how you think about everything else.
Show Answer
Great Britain (most likely Roman Britain, in what is now either Wales, Scotland, or England). The most common wrong answer is Ireland, and it’s wrong in such a fundamental way that people sometimes argue with you about it. Patrick was brought to Ireland as a slave. He wasn’t born there.
2. Before becoming a religious figure, what was St. Patrick’s status when he first arrived in Ireland?
This one changes the tone of the room. It takes Patrick out of stained glass and puts him into something much harder to look away from.
Show Answer
He was a slave. Kidnapped at around age 16 by Irish raiders and forced to work as a shepherd for six years before escaping.
3. What was St. Patrick’s birth name?
I love this question because it sounds like it should be impossibly obscure, but the answer has a warmth to it that makes people smile.
Show Answer
Maewyn Succat. He took the name Patricius (Patrick) later when he entered the priesthood. Something about learning his real name makes him feel more like a person and less like a mascot.
4. According to legend, what did St. Patrick drive out of Ireland?
This one’s a gimme, and every set needs a few. But it earns its place because of what comes next.
Show Answer
Snakes. Ireland almost certainly never had snakes after the last Ice Age, which makes the legend either purely metaphorical or a very easy job.
5. What three-leafed plant did St. Patrick supposedly use to explain the Holy Trinity?
Show Answer
The shamrock. Worth noting: “shamrock” isn’t a single species. It’s a folk name applied to several different clovers and plants, and there’s genuine botanical debate about which one is the “real” shamrock. The Irish fought about this for decades.
6. On what date is St. Patrick’s Day celebrated?
I include this in every set because you’d be amazed how many people hesitate. They know it’s mid-March. They know it’s around the 15th to the 18th. But the exact date? Watch them count on their fingers.
Show Answer
March 17th. It’s believed to be the date of Patrick’s death in 461 AD, though even that year is disputed.
7. St. Patrick’s Day falls during which Christian liturgical season, which is significant because it typically means a relaxation of certain rules?
This is the question that explains why the holiday involves so much drinking. The answer is the context everyone’s been missing.
Show Answer
Lent. St. Patrick’s Day falls during Lent, and historically the restrictions on eating and drinking were lifted for the day. That’s how a saint’s feast day became a party.
The Color Problem
8. What color was originally associated with St. Patrick and the St. Patrick’s Day celebration?
If you read the opening, you already know this one. But in a room full of people, this question is pure chaos. I’ve had someone in a green sequin hat argue with me for two full minutes.
Show Answer
Blue. Specifically “St. Patrick’s Blue.” The shift to green happened gradually through the 18th and 19th centuries, driven by Irish nationalism and the wearing of shamrocks. Green was the color of rebellion, and it stuck.
9. According to Irish folklore, what happens to you if you don’t wear green on St. Patrick’s Day?
Show Answer
You get pinched. The tradition is mostly American, and the logic goes that wearing green makes you invisible to leprechauns, who will pinch anyone they can see. It’s the kind of rule that was clearly invented by a child, and I mean that as a compliment.
10. What U.S. city famously dyes its river green every St. Patrick’s Day?
The easy answer. But save the follow-up for question 11.
Show Answer
Chicago. The Chicago River has been dyed green since 1962, and the tradition started almost by accident when plumbers used green dye to trace pollution sources.
11. The dye used to turn the Chicago River green was originally what color before it hit the water?
This is the one that gets the double-takes. People assume green dye turns water green. It does. But the dye itself tells a different story.
Show Answer
Orange. The powdered dye is actually orange and turns green upon contact with the water. There’s a beautiful irony in using orange to make something green on St. Patrick’s Day, given the political history of those two colors in Ireland.
12. Roughly how long does the green color last in the Chicago River?
Show Answer
About 5 hours (though some sources say up to 48 hours depending on conditions). They used to use an oil-based dye that lasted days, but switched to a vegetable-based dye in the 1960s for environmental reasons. The exact formula is still a closely guarded secret.
Across the Atlantic
13. In Ireland, St. Patrick’s Day was traditionally observed primarily as what type of occasion, rather than the party it’s become?
This one recalibrates the room. The American version of the holiday and the Irish version were, until recently, completely different animals.
Show Answer
A religious feast day. Pubs in Ireland were actually required by law to close on March 17th until 1970. The holiday as a massive secular celebration is largely an American export that Ireland eventually imported back.
14. Until what year were pubs in Ireland legally required to be closed on St. Patrick’s Day?
Show Answer
1970. Let that land for a second. The country most associated with St. Patrick’s Day drinking didn’t allow pub drinking on St. Patrick’s Day for most of the 20th century.
15. What is the only place in Ireland where you could legally buy a drink on St. Patrick’s Day before 1970?
This is one of my favorite pieces of trivia full stop. The answer is so specific and so absurd that it sounds made up.
Show Answer
The RDS (Royal Dublin Society) annual dog show, known as the Irish Kennel Club show. It was held on St. Patrick’s Day, and because it was a special event, alcohol could be served. People who had no interest in dogs would attend just to get a drink.
16. What major U.S. city held the first St. Patrick’s Day parade?
Most people say Boston. Some say Chicago. Almost nobody says the right answer, which is what makes it perfect.
Show Answer
New York City, in 1762. Though some historians argue it may have been Boston in 1737. The New York parade is better documented and is widely considered the oldest. Either way, the first parades were in America, not Ireland. Common wrong answer: Dublin, which didn’t hold its first parade until 1931.
17. Ireland’s capital, Dublin, didn’t hold its first official St. Patrick’s Day parade until what year?
Show Answer
1931. Almost 170 years after New York’s. America built the celebration and Ireland eventually decided to join in.
18. What iconic global landmark-lighting campaign, started by Tourism Ireland, turns famous buildings green on St. Patrick’s Day?
Show Answer
The “Global Greening” initiative, launched in 2010. It started with just a handful of landmarks and now includes the Sydney Opera House, the Leaning Tower of Pisa, the Pyramids of Giza, Niagara Falls, and hundreds more. It’s become the single most visible piece of St. Patrick’s Day culture worldwide.
Leprechauns, Luck, and Legends
19. In traditional Irish folklore, what is a leprechaun’s occupation?
People say “cobbler” with surprising confidence or surprising confusion. There’s rarely anything in between.
Show Answer
A shoemaker (cobbler). Specifically, they’re said to make shoes for other fairies. The tapping of their tiny hammers is supposedly how you find one.
20. According to legend, what will you find at the end of a rainbow, guarded by a leprechaun?
Show Answer
A pot of gold. Simple question, but it sets up the next one nicely.
21. What happens if you catch a leprechaun, according to Irish folklore?
Show Answer
The leprechaun must grant you three wishes in exchange for its freedom. But the stories always emphasize that leprechauns are tricksters who’ll outsmart you if you look away for even a second. The moral is basically: don’t trust small magical accountants.
22. How many leaves does a shamrock have?
This is the question that separates people who are paying attention from people who are thinking about something else entirely.
Show Answer
Three. Not four. A four-leaf clover is a separate thing. The shamrock, the symbol of Ireland and St. Patrick’s Day, has three leaves. I’ve watched entire tables get this wrong because their brain jumps straight to “lucky clover.” The four-leaf clover is considered lucky precisely because it’s a rare mutation of the three-leafed norm.
23. What is the Irish word for shamrock?
Show Answer
Seamróg, which means “little clover” or “young clover.” The English word “shamrock” is an anglicization of this.
24. In the 1959 Disney film, what was the name of the leprechaun character played by Jimmy O’Dea in “Darby O’Gill and the Little People”?
Bonus points if anyone remembers who else starred in this film before he became the most famous man on the planet.
Show Answer
King Brian. And yes, a very young Sean Connery had a supporting role. It was one of his last films before being cast as James Bond.
Food, Drink, and the Things We Get Wrong
25. What is the traditional Irish meal associated with St. Patrick’s Day in America that isn’t actually traditional in Ireland?
This one always starts a conversation. People get defensive about their family traditions, and they should. But the history is the history.
Show Answer
Corned beef and cabbage. In Ireland, the traditional St. Patrick’s Day meat was bacon (specifically back bacon, closer to what Americans call Canadian bacon). Irish immigrants in America switched to corned beef because it was cheaper and more available, often bought from Jewish delis in New York. The dish is Irish-American, not Irish.
26. What is the traditional meat eaten on St. Patrick’s Day in Ireland?
Show Answer
Bacon (or ham). Specifically Irish back bacon, which is leaner and more like a ham steak than American strip bacon. Some families also eat lamb.
27. What Irish bread, made without yeast and using baking soda as a leavening agent, is a staple of St. Patrick’s Day meals?
Show Answer
Irish soda bread. The cross cut into the top before baking was traditionally said to let the devil out or bless the bread, depending on who’s telling you.
28. Colcannon, a traditional Irish dish served around St. Patrick’s Day, is made primarily from mashed potatoes and what vegetable?
Show Answer
Cabbage (or kale). Historically, small items like coins, rings, or thimbles were hidden in colcannon, and whatever you found predicted your future. A coin meant wealth. A ring meant marriage. A thimble meant you’d be single. Nobody wanted the thimble.
29. What is the name of the Irish stout, brewed in Dublin since 1759, that’s become synonymous with St. Patrick’s Day celebrations worldwide?
Show Answer
Guinness. Arthur Guinness signed a 9,000-year lease on the St. James’s Gate Brewery. Nine thousand years. At 45 pounds per year. That might be the most confident business decision in human history.
30. Approximately how many pints of Guinness are consumed worldwide on St. Patrick’s Day?
Give this one as a range. Let people guess. The number is absurd in a way that makes you respect humanity.
Show Answer
Around 13 million pints. On a normal day, about 10 million pints of Guinness are consumed globally. St. Patrick’s Day bumps that by roughly 30%. That’s a lot of patience spent waiting for pints to settle.
31. What bright green minty milkshake does McDonald’s famously bring back every St. Patrick’s Day season?
Show Answer
The Shamrock Shake. It was introduced in 1970 and has become one of the most reliable signs that mid-March has arrived, right up there with daylight saving time confusion.
Numbers That Don’t Feel Real
32. How many Americans claim Irish ancestry, according to the U.S. Census?
The answer to this question explains the entire American version of St. Patrick’s Day. It’s a scale thing.
Show Answer
Roughly 31 to 33 million. That’s about seven times the population of Ireland itself (around 5 million). There are more Irish-Americans than there are Irish people, which is why the American celebration is so much louder.
33. What is the population of the Republic of Ireland, roughly?
Show Answer
About 5.1 million. It still hasn’t recovered to its pre-famine population of around 8 million in the 1840s. That’s a fact that should sit with you for a while.
34. The island of Montserrat in the Caribbean celebrates St. Patrick’s Day as a public holiday. Why?
Nobody ever gets this one, and the reason is genuinely moving.
Show Answer
Montserrat was heavily settled by Irish immigrants (many of whom were indentured servants or political prisoners sent by Cromwell), and the island has deep Irish cultural roots. St. Patrick’s Day also commemorates a failed slave uprising on March 17, 1768. It’s one of the only places outside Ireland where the day is a national holiday, and the celebration blends Irish and Caribbean traditions in a way that feels completely its own.
35. What percentage of the beer sold in the United States on St. Patrick’s Day is estimated to be consumed on that single day? Is it closer to 1%, 3%, or 5% of annual beer sales?
Show Answer
It’s not quite that dramatic, but St. Patrick’s Day is consistently one of the top drinking holidays in the U.S. Estimates suggest Americans spend over $6 billion on St. Patrick’s Day, with a significant portion going to alcohol. The day ranks behind only New Year’s Eve and the Super Bowl for alcohol consumption.
Music, Movies, and the Culture
36. What traditional Irish instrument, a type of lute with a long neck and a round body, is commonly associated with Irish folk music played on St. Patrick’s Day?
Show Answer
The Irish bouzouki. Though many people will say the bodhrán (a frame drum) or the tin whistle, and those are also correct associations. But the bouzouki is the one that catches people off guard because they associate it with Greek music. It was adapted for Irish music in the 1960s by Johnny Moynihan.
37. What Irish frame drum, played with a small stick called a tipper or cipín, is one of the most recognizable instruments in traditional Irish music?
Show Answer
The bodhrán. Pronounced roughly “BOW-rawn.” I’ve heard every possible mispronunciation of this word, and each one is a small gift.
38. The song “Danny Boy” is set to what traditional Irish melody?
This is the question that separates the people who love the song from the people who know the song.
Show Answer
The “Londonderry Air.” The lyrics to “Danny Boy” were actually written by an English lawyer named Frederic Weatherly in 1913, who had never been to Ireland. The melody itself is much older and its origins are disputed.
39. What 1952 John Ford film, starring John Wayne and Maureen O’Hara, is set in Ireland and often aired on or around St. Patrick’s Day?
Show Answer
“The Quiet Man.” It was filmed in Cong, County Mayo, and the village still trades on the connection. If you visit, you can take a Quiet Man walking tour. John Wayne’s cottage is a museum.
40. What U2 song, released in 1987, became an unofficial anthem of Irish pride and is frequently played on St. Patrick’s Day?
Show Answer
Several could qualify, but “Where the Streets Have No Name” or “I Still Haven’t Found What I’m Looking For” are the usual suspects. If you’re being specific to Irish identity, “Sunday Bloody Sunday” (1983) might be the most powerful, though it’s about the Troubles rather than celebration. Accept any reasonable U2 answer and then argue about it, which is what U2 conversations are for.
The Tricky Stuff
41. What is the name of the traditional Irish dance performance that became a global phenomenon in 1994, originally performed during the Eurovision Song Contest interval?
Show Answer
Riverdance. The seven-minute interval performance at Eurovision in Dublin became the most talked-about moment of the broadcast. It was extended into a full show that’s been seen by over 25 million people live. It completely changed how the world thought about Irish dance.
42. What is the Irish language (Gaelic) phrase for “Happy St. Patrick’s Day”?
I use this one as a written round question sometimes. The spellings people attempt are works of art.
Show Answer
“Lá Fhéile Pádraig Sona Duit” (pronounced roughly “Law AY-leh PAW-drig SUN-ah dit”). It literally translates to “Happy St. Patrick’s feast day to you.”
43. What is the term for a traditional Irish wake, where the body of the deceased is kept at home and visitors come to pay respects, often with music, storytelling, and drinking?
Not a St. Patrick’s Day question exactly, but it speaks to the Irish relationship with celebration and mourning that runs underneath everything about this holiday.
Show Answer
An Irish wake (or simply a “wake”). The tradition involves keeping the body in the home, often in the parlor, while friends and family gather. It’s equal parts grief and celebration, and it’s one of the most honest rituals any culture has produced.
44. What symbol appears on the coat of arms of Ireland and on Irish Euro coins, and is NOT a shamrock?
This one catches people beautifully. They’re so locked into shamrock mode that the real national symbol blindsides them.
Show Answer
The harp. Specifically, the Trinity College Harp (also called the Brian Boru Harp). Ireland is the only country in the world with a musical instrument as its national symbol. The shamrock is an unofficial symbol; the harp is the official one. Common wrong answer: the shamrock, obviously.
45. What is the shortest St. Patrick’s Day parade in the world, and where does it take place?
This is one of those facts that sounds like a setup for a joke, and it basically is.
Show Answer
Dripsey, County Cork, Ireland. The parade route runs between the village’s two pubs, a distance of about 100 yards (roughly 91 meters). It’s been billed as the shortest parade in the world, and honestly, it might be the most efficient celebration ever designed.
46. What U.S. city dyes its canal green for St. Patrick’s Day, and is sometimes confused with Chicago’s river dyeing?
Show Answer
Indianapolis dyes its downtown canal green. San Antonio also dyes its River Walk green. Several cities have picked up the tradition, but Chicago remains the most famous for it.
47. The phrase “Erin go Bragh,” commonly heard on St. Patrick’s Day, translates to what in English?
Show Answer
“Ireland forever.” From the Irish “Éirinn go Brách.” It’s been a rallying cry of Irish nationalism and diaspora pride for centuries, and it’s one of the few Irish-language phrases that most Americans can recognize even if they can’t spell it.
48. What U.S. president, whose great-great-grandfather emigrated from County Wexford, famously visited Ireland in 1963 and received a rapturous welcome?
Show Answer
John F. Kennedy. His visit to his ancestral homeland in June 1963 was one of the most emotional moments of his presidency. He was assassinated five months later. The JFK connection remains a point of deep pride in Ireland, and the homestead in Dunganstown is still a place of pilgrimage.
The One You Save for Last
49. According to tradition, what is the only day of the year when the “drowning of the shamrock” takes place, and what does this ritual involve?
This is the tradition that nobody talks about because it sounds too perfectly Irish to be real. But it is.
Show Answer
St. Patrick’s Day. The “drowning of the shamrock” is a tradition where, at the end of the night, the shamrock that’s been worn on your lapel all day is placed in the last drink of the evening. You drink the whiskey or beer, and the shamrock is either swallowed or tossed over your left shoulder for good luck. It’s a farewell to the day, a toast to the saint, and an excuse for one more drink, all in one gesture.
50. St. Patrick is said to have died on March 17, 461 AD, in Saul, County Down. But there’s a catch: two Irish cities both claim to be his final resting place. Name either one.
I always end with this question because it does something that the best trivia should do. It doesn’t just test what you know. It reveals that the story itself is still unfinished, still argued over, still alive. Two cities claiming the same saint’s bones. Fifteen centuries of dispute. No resolution in sight. And every March 17th, both places set up their parades and pour their pints and insist they’re right. That’s not just trivia. That’s Ireland.
Show Answer
Downpatrick and Armagh. Downpatrick, in County Down, has a granite slab marked “PATRIC” in the grounds of Down Cathedral, though it was placed there in 1900 and the actual burial site beneath is uncertain. Armagh, the ecclesiastical capital of Ireland, also claims the honor. The truth is that nobody knows for sure, and both cities have made peace with the argument itself being the point.
General knowledge is the hardest round to write because it has to be genuinely broad. I've been at it for 10 years from Boston, MA and I still approach every question like I'm writing for a room full of different people, because I am. I've written for JetPunk trivia, and I take the same care with every set I write.
