The Bedsitting Room is a satirical play by Spike Milligan and John Antrobus. It began as a one-act play which was first produced on 12 February 1962 at the Marlowe Theatre in Canterbury, England. The Bedsitting Room was then adapted to a longer play and Bernard Miles put it on at the Mermaid Theatre, where it was first performed on 31 January 1963 before transferring several weeks later to the Duke of York's Theatre in London's West End.

Terence Alan "Spike" Milligan was an Irish comedian, writer, musician, poet, playwright and actor. The son of an English mother and Irish father, he was born in British Colonial India, where he spent his childhood before relocating in 1931 to England, where he lived and worked for the majority of his life. Disliking his first name, he began to call himself "Spike" after hearing the band Spike Jones and his City Slickers on Radio Luxembourg.
