The Audubon Theatre and Ballroom, generally referred to as the Audubon Ballroom, was a theatre and ballroom located at 3940 Broadway at West 165th Street in the Washington Heights neighborhood of Manhattan, New York City. It was built in 1912 and was designed by Thomas W. Lamb. The theatre was known at various times as the William Fox Audubon Theatre, the Beverly Hills Theater, and the San Juan Theater. The ballroom is noted for being the site of the assassination of Malcolm X on February 21, 1965. Most of the building was demolished starting in 1992, with two-thirds of the facade preserved. It is currently the Audubon Business and Technology Center, which is part of Columbia University's Audubon Research Park.
