California's 59th State Assembly district is one of 80 California State Assembly districts. It is currently represented by Republican Phillip Chen of Yorba Linda.
The district encompasses most of the more Republican leaning areas in northeast Orange County along the Inland Empire border, taking in the entirety of suburban cities such as Yorba Linda, Brea, Placentia, Anaheim Hills, Villa Park, North Tustin, and portions of Orange and Fullerton. It also encompasses the suburban San Bernardino county city of Chino Hills and a small portion of Chino.
Due to redistricting, the 59th district has been moved around different parts of the state. The current iteration resulted from the 2021 redistricting by the California Citizens Redistricting Commission.
