La MaMa Experimental Theatre Club is an Off-Off-Broadway theater founded in 1961 by African-American theatre director, producer, and fashion designer Ellen Stewart. Located in the East Village neighborhood of Manhattan in New York City, the theater began in the basement boutique where Stewart sold her fashion designs. Stewart turned the space into a theater at night, focusing on the work of young playwrights.
