Pierre-Félix Louÿs (French: [pjɛʁ lu.is]; 10 December 1870 – 4 June 1925) was a Belgian poet and writer, most renowned for lesbian and classical themes in some of his writings.

He studied at the École Alsacienne in Paris, and there he developed a good friendship with a future Nobel Prize winner and champion of homosexual rights André Gide.

During 1891, Louÿs helped initiate a literary review, La Conque,[5] where he proceeded to publish Astarte, an early collection of erotic verse already marked by his distinctive style.

[citation needed] Although Debussy claimed exclusive rights to compose an opera based on Aphrodite (and Louÿs said he had to turn down several similar applications), the project never got under way.

[11][12] Inspired by Abel Lefranc's arguments for the Derbyite theory of Shakespeare authorship, Louÿs proposed in 1919 that the works of Molière were actually written by Corneille.
