Introduction
Halloween is one of the most celebrated nights of the year. Millions of people carve pumpkins, put on costumes, and fill bowls with candy, yet few know why we do any of it. Why turnips came before pumpkins, why "trick or treat" only appeared in the 1920s, and why a Captain Kirk mask became a horror icon are the kinds of facts that win trivia nights.
We have put together 40 Halloween trivia questions with answers across five rounds: the holiday's Celtic origins, its symbols and superstitions, classic horror movies and monsters, candy and costume history, and real-life spooky science. Each question includes a short explanation, so you learn something even when you guess wrong.
Use them for a Halloween party, a classroom activity, an office quiz, or a solo challenge. Rounds 1 and 4 are great for kids and families, while Rounds 3 and 5 will test seasoned horror fans and trivia buffs.
Round 1: Origins & History of Halloween
Long before plastic skeletons and candy aisles, Halloween was Samhain, a night when ancient Celts believed the dead walked among the living. Over two thousand years it absorbed Christian feast days, medieval begging customs, and Irish folklore.
Start your Halloween trivia night with these eight questions on where the holiday really came from.
From Celtic Samhain fires to Irish immigrants: how a harvest festival became a global holiday.
Halloween grew out of which ancient Celtic festival marking the end of the harvest?
Before pumpkins, the Irish and Scots carved turnips, potatoes, and beets with ghoulish faces and set them in windows to scare off wandering spirits. Surviving examples look far creepier than any modern pumpkin.
Round 2: Symbols, Superstitions & Traditions
Every Halloween symbol has a story. Some superstitions turn completely upside down depending on the country you are in, and even the humble pumpkin hides a surprising botanical identity.
Test how well you know the customs and superstitions that make October 31 so distinctive.
Black cats, barmbrack charms, pumpkin patches, and the rare Halloween full moon.
What is the name for an intense, persistent fear of Halloween?
The production of Halloween (1978) was so low-budget that the crew bought a Captain Kirk mask for about $2 and spray-painted it white. William Shatner reportedly said he was honored.
Round 3: Horror Movies, Books & Monsters
Horror classics are as much a part of Halloween as candy. Gothic novels from the 1800s gave us vampires and reanimated corpses, and Hollywood turned them into the monsters we dress up as today.
Horror fans, this is your round. Do you know the cheap tricks behind cinema's most terrifying scenes?
Michael Myers, Dracula, Frankenstein, Hocus Pocus, and behind-the-scenes horror secrets.
Who directed and composed the score for the original "Halloween" (1978)?
Harry Houdini promised his wife Bess he would try to contact her from beyond. Since his death on October 31, 1926, magicians have held an official Houdini séance every Halloween. He has yet to show up.
Round 4: Candy, Costumes & Celebrations
Today Halloween is a multi-billion-dollar celebration of sugar and dress-up. But trick-or-treating nearly disappeared during World War II, and candy corn once had a very unappetizing name.
A sweet round for the whole family, though a few answers may surprise even die-hard trick-or-treaters.
Candy corn secrets, trick-or-treat history, costume origins, and record-breaking parades.
When candy corn was first sold in the late 1800s, what was it originally marketed as?
Round 5: Spooky Science & Strange History
Some of the creepiest Halloween stories are completely real. Biology, chemistry, and history supply plenty of material that is stranger than fiction.
Finish strong with the toughest round: eight questions where science and history meet the supernatural.
Vampire bats, ghost lights, Houdini's final act, the Salem witch trials, and the real Dracula.
Bats are a Halloween icon. What makes them unique among mammals?

Fascinating Halloween Facts to Share at Your Party
From record-breaking pumpkins to candy science:
Competitive growers now produce pumpkins weighing over 2,700 pounds (more than 1,200 kg), heavier than many compact cars. Some growers even hollow them out and paddle them across lakes in pumpkin regattas.
Candy corn is still made by "corn starch molding": layers of colored syrup are poured into kernel-shaped trays pressed into cornstarch, the same basic technique used by its 19th-century inventors.
In the United States, only Christmas outranks Halloween for decoration spending, and inflatable yard displays and 12-foot skeletons have become a seasonal phenomenon.
In 2005, the U.S. extended daylight saving time into early November starting in 2007. Candy makers had lobbied for the change for years, hoping that more daylight on Halloween would mean more trick-or-treating.
