109 free Trivia for Teens trivia questions with answers — trivia quiz, new questions added Aug 2026.
These 103 trivia questions for teens are written for ages 13 to 19: old enough to know who plays Wednesday Addams and which studio made Fortnite, and old enough to be asked how many bones are in the body, which continent has the most countries and which king sealed Magna Carta. Nothing here is aimed at little kids, and nothing needs a degree. The set deliberately mixes categories so no one player runs the table: movies and TV, music, gaming and tech, sport, science, geography, history, animals, books and a little math. Most questions sit at a medium level, with a handful of easy openers and a few that will split the room. It works as a solo quiz, a youth group or classroom warm-up, a sleepover game or a family night where the teenagers finally have the edge. Every answer was checked against an encyclopaedic source and carries the sentence it came from, so when someone argues about how many Olympic medals Michael Phelps won, the receipt is right there.
