The Leslie/Lohman Gay Art Foundation is a public non-profit foundation which was established in 1990 to provide an outlet for art work that is unambiguously gay and which is frequently denied access to mainstream venues. The Foundation's Leslie/Lohman Gallery mounts exhibitions of work in all media by gay and lesbian artists with an emphasis on subject matter that speaks directly to gay and lesbian sensibilities, including, erotic, political, romantic, and social imagery and providing special support for emerging and underrepresented artists.

It's programs include regularly scheduled exhibitions, video events, workshop presentations of plays, a slide registry, artists' and curator's talks, panel discussions, a quarterly arts journal, a membership program, an archive, a website, and a permanent collection of art.
