John A. Pérez (born September 28, 1969) is a union organizer and politician from Los Angeles, California, who has been the Speaker of the California State Assembly since March 1, 2010. A Democrat, he represents the 46th district in the California State Assembly.

Pérez grew up in El Sereno and Highland Park before attending the University of California, Berkeley. He did not graduate from Berkeley but instead dropped out after his junior year due to family medical reasons, choosing not to return for a fourth year in the fall of 1990. Various biographies of Pérez dating back to the 1990s had falsely stated that he was a Berkeley graduate, an assertion included in several press releases issued by mayors of Los Angeles and in 2004 remarks inserted by then-Congresswoman Hilda Solis into the Congressional Record. When the San Francisco Chronicle wrote about these inconsistencies in May 2011, Pérez's office clarified that he was not, in fact, a Berkeley graduate.

Pérez is the cousin of Los Angeles mayor Antonio Villaraigosa and has spent seven years handling political matters for the United Food and Commercial Workers, a union representing supermarket workers, and also has served as political director of the California Labor Federation. He was a member of the Los Angeles Community Redevelopment Agency until 2008, when he resigned from the board in order to run for the Assembly.
