California's 55th State Assembly district is one of 80 California State Assembly districts. It is currently represented by Democrat Isaac Bryan of Los Angeles.
Prior to the 2022 California elections, the district straddled the intersection of three counties and several distinct regions. Centered on the Chino Hills, it included the southeastern margins of the San Gabriel Valley as well as parts of the northern Santa Ana Valley. After the 2020 redistricting cycle, the district encompassed the neighborhoods of Baldwin Hills, the Crenshaw District, Culver City, Ladera Heights, Mar Vista, Del Rey, Palms, Pico-Robertson, Beverly Grove, Mid-Wilshire, and large parts of South Los Angeles.
Due to redistricting, the 55th district has been moved around different parts of the state. The current iteration resulted from the 2021 redistricting by the California Citizens Redistricting Commission.
