Completed in 1968, the Union Bank Plaza is a Los Angeles, historic-cultural monument listed 40-story 515 ft (157m) office skyscraper located on south Figueroa Street in downtown Los Angeles, California.

It was the first skyscraper built in the central business district of Los Angeles as part of the Bunker Hill redevelopment project following the 1957 repeal of limitations on construction greater than 150 feet in height.
