A pub quiz is a quiz held in a pub or bar. These events are also called quiz nights, trivia nights, or bar trivia and may be held in other settings. The pub quiz is a modern example of a pub game, and often attempts to lure customers to the establishment on quieter days. The pub quiz has become part of British culture since its popularization in the UK in the 1970s by Burns and Porter, although the first mentions in print can be traced to 1959. It then became a staple in Irish pub culture, and its popularity has continued to spread internationally. Although different pub quizzes can cover a range of formats and topics, they have many features in common. Most quizzes have a limited number of team members, offer prizes for winning teams, and distinguish rounds by category or theme.

A quiz is a form of game or mind sport in which players attempt to answer questions correctly on one or several specific topics. Quizzes can be used as a brief assessment in education and similar fields to measure growth in knowledge, abilities, and skills, or simply as a hobby. They can also be televised for entertainment purposes, often in a game show format.
