The Crucible Theatre, or simply The Crucible, is a theatre in Sheffield, South Yorkshire, England which opened in 1971. It hosts regular theatrical performances and the annual World Snooker Championship, which has been held at the venue since 1977. The theatre's name refers to crucible steel, which was developed in Sheffield in 1740 and drove the industrialisation of the city. In May 2022 plans were unveiled to build a new 3,000-seat venue nearby with a bridge connecting the two buildings.

The World Snooker Championship is the longest-running and most prestigious tournament in professional snooker. It is also the richest, with total prize money of £2,395,000 in 2023, including £500,000 for the winner. First held in 1927, it is now one of the three tournaments that make up snooker's Triple Crown Series. The reigning world champion is Kyren Wilson.
