The Room is the title of the first play written by Harold Pinter. The play has strong similarities to Pinter's second play, The Birthday Party. Both take place in run-down buildings claiming to be a "boarding house" which become the scene of a visitation by apparent strangers.

In The Room, after one of the two main characters, Rose Hudd, is visited by a young couple, Mr. and Mrs. Sands, who are looking for a flat, a blind black man, named Riley, who has purportedly been waiting in the basement, suddenly arrives upstairs to Rose's room, to deliver a mysterious message to Rose. The play ends in violence after Rose's husband, Bert, returns.

The Room is invested with many of the elements that later became elements of Pinter's work including the familiarity of dialogue that is disturbing, the subtle characterization of characters with whom the audience learns nearly nothing, and a mood that can be funny, moving, and menacing simultaneously.

Pinter wrote The Room over several days in 1957 at the suggestion of his friend Henry Woolf for his production as part of a postgraduate program in directing at the University of Bristol, Bristol, England.
