The Hammer Museum, which is affiliated with the University of California, Los Angeles, is an art museum and cultural center known for its artist-centric and progressive array of exhibitions and public programs. Founded in 1990 by the entrepreneur-industrialist Armand Hammer to house his personal art collection, the museum has since expanded its scope to become "the hippest and most culturally relevant institution in town." Particularly important among the museum's critically acclaimed exhibitions are presentations of both historically overlooked and emerging contemporary artists. The Hammer Museum also hosts over 300 programs throughout the year, from lectures, symposia, and readings to concerts and film screenings. As of February 2014, the museum's collections, exhibitions, and programs are completely free to all visitors.

Armand Hammer was an American business manager and owner. He spent decades with Occidental Petroleum in the mid 20th century. Called "Lenin's chosen capitalist" by the press, he was also known for his art collection and his close ties to the Soviet Union.
