Mrs. Warren's Profession is a play written by George Bernard Shaw in 1893, and first performed in London in 1902. It is one of the three plays Shaw published as Plays Unpleasant in 1898, alongside The Philanderer and Widowers' Houses. The play is about a former prostitute, now a madam, who attempts to come to terms with her disapproving daughter. It is a problem play, offering social commentary to illustrate the idea that the act of prostitution was not caused by moral failure but by economic necessity. Elements of the play were borrowed from Shaw's 1882 novel Cashel Byron's Profession, about a man who becomes a boxer due to limited employment opportunities.

George Bernard Shaw, known at his insistence as Bernard Shaw, was an Irish playwright, critic, polemicist and political activist. His influence on Western theatre, culture and politics extended from the 1880s to his death and beyond. He wrote more than sixty plays, including major works such as Man and Superman (1902), Pygmalion (1913) and Saint Joan (1923). With a range incorporating both contemporary satire and historical allegory, Shaw became the leading dramatist of his generation, and in 1925 was awarded the Nobel Prize in Literature.
