40 Trivia Questions With Answers, Sorted by Subject

Boy laughing during a trivia quiz

A good trivia round gives everybody a way in, then gets harder without turning into guesswork. These questions are grouped by subject, with the answer directly below each one so a host can read them aloud without losing the room.

The list avoids answers that change every few months, disputed superlatives and questions whose wording hides more than one defensible answer. Use one section as a quick round or combine all five for a full family or classroom quiz.
