The Green Room Club was a London-based club, primarily for actors, but also for lovers of theatre, arts and music. It was established in 1877 in a restaurant in Piccadilly Circus, and moved to premises on Adam Street in 1955, where it remained until its closure in 2004. The club's name was not trademarked, and there have been at least two attempts to "re-found" a version of the club in new premises.
