Union Station in Los Angeles, which opened in May 1939, is known as the "Last of the Great Railway Stations" built in the United States, but even with its massive and ornate waiting room and adjacent ticket concourse, it is considered small in comparison to other union stations. It was formerly designated the Los Angeles Union Passenger Terminal (LAUPT), but its current owner, Catellus Development, officially changed the name to Los Angeles Union Station (LAUS).

The facility served as a backdrop for the 1950 film Union Station, which starred William Holden and Nancy Olson. Many television shows and motion pictures have incorporated the station as a backdrop, including Speed, Pearl Harbor, Blade Runner, Star Trek: First Contact, and the Fox television series 24.

Union Station is located opposite L.A.'s historic Olvera Street.
