The Gay Lord Quex (play)

The Gay Lord Quex is an 1899 comedy play by the British playwright Arthur Wing Pinero. It depicts the vicissitudes of a reformed philanderer attempting to embark on monogamy. The original production provoked controversy, some critics finding the plot at best questionable and at worst immoral.

The play premiered at the Globe Theatre, London, on 8 April 1899, and ran for 300 performances. It was produced by John Hare, who also played the title role. Others in the cast included Charles Cherry, Frank Gillmore, May Fortescue, Irene Vanbrugh and Mabel Terry-Lewis. The play was revived in the West End in five productions during the 20th century and has been adapted for the cinema, radio and television.
