The National History Bee and Bowl are buzzer-based history quiz competitions for Elementary and Middle School-aged students throughout the USA.

The Bee is a competition for individual students. The Bowl is a team event (though single-player teams are allowed).

NHBB operates as a division of International Academic Competitions, which organizes events in over 30 countries around the world, including the biennial International History Olympiad, for which students can qualify through participation in NHBB events.
