Juan Manuel Puig Delledonne (General Villegas, December 28, 1932 - Cuernavaca, July 22, 1990) was an Argentine writer and LGBT+ activist, author of the novels Boquitas pintadas, The kiss of the spider woman and Angelic pubis.

He spent his childhood in his small hometown and emigrated to the Argentine capital to carry out his secondary studies. After starting different higher studies, he chose to train in cinematography, for which he moved to Italy. He did not materialize his training and ended up performing as a writer. He lived in Rome, Paris, London, Stockholm, Mexico, New York, Rio de Janeiro, and Cuernavaca. He is the author of eight novels and four plays, as well as short stories and film scripts. He is well recognized for his use of literary polyphony and the interior monologue.

Although since puberty he assumed himself to be homosexual, he wrote and campaigned on this issue, even declaring that something as "banal" as sexuality cannot define a person's identity and, on the other hand, he believed that the activity of groups Homosexuals tended to make the mistake of separating the homosexual issue from other groups, communities or social sectors. However, he was a founding member of the Homosexual Liberation Front in 1971 together with the sociologist and historian Juan José Sebreli, the lawyer and writer Blas Matamoro and the poet and writer Néstor Perlongher.
