California's 53rd State Assembly district is one of 80 California State Assembly districts.

Since 2024, it is represented by Democrat Michelle Rodriguez of Pomona.

Since the 2021 California redistricting, the district includes Pomona, Montclair, and much of Chino, Ontario, and Upland.

Due to redistricting, the 54th district has been moved around different parts of the state.

The current iteration resulted from the 2022 redistricting by the California Citizens Redistricting Commission.
