Ron Vawter (December 9, 1948-April 16, 1994) was a founding member of The Wooster Group. He performed in most of the group's works until his death from complications due to AIDS in 1994 at the age of 45.

In addition to his work with The Wooster Group he frequently appeared in films, including Philadelphia, The Silence of the Lambs and sex, lies, and videotape, generally playing small character roles.

He is perhaps best known for the play "Roy Cohn/Jack Smith" a series of two monologues that contrast the characters of the two homosexual men who both died of AIDS.
