Tongues Untied is a 1989 American experimental documentary film directed by Marlon T. Riggs, and featuring Riggs, Essex Hemphill and Brian Freeman. The film seeks, in its author's words to, "...shatter the nation's brutalizing silence on matters of sexual and racial difference."

Marlon Troy Riggs was a black gay filmmaker, educator, poet, and activist. He produced, wrote, and directed several documentary films, including Ethnic Notions, Tongues Untied, Color Adjustment, and Black Is...Black Ain't. His films examine past and present representations of race and sexuality in the United States. The Marlon Riggs Collection is open to the public at Stanford University Libraries.
