Sheffield Theatres is a theatre complex in Sheffield, South Yorkshire, England. It comprises three theatres: the Crucible, the Lyceum and the Tanya Moiseiwitsch Playhouse. These theatres make up the largest regional theatre complex outside the London region and show a variety of in-house and touring productions.

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.
