Tim Miller (born September 22, 1958 in Pasadena, California) is an American performance artist and writer, whose pieces frequently involve gay identity, marriage equality and immigration issues. He was one of the NEA Four, four performance artists whose National Endowment for the Arts grants were vetoed in 1990 by NEA chair John Frohnmayer.
Miller was born in Pasadena, California but grew up in nearby Whittier.
He has developed shows based on his personal life as a gay man and as an activist. A member of ACT UP and other campaigning organizations, Miller has participated in numerous demonstrations to call for funding of AIDS research and treatment and to promote equal rights. His civil disobedience has led to his arrest on several occasions.
Miller's interest in performance began in high school, where he took classes in theater and dance. He played the lead role of John Proctor in Lowell High School's production of The Crucible by Arthur Miller. At nineteen he moved to New York and studied dance with Merce Cunningham.
