California's 75th State Assembly district is one of 80 California State Assembly districts. It is currently represented by Republican Carl DeMaio of San Diego.
The district encompasses inland parts of San Diego County. The area is mountainous, containing most of the county's land area, covering the rural eastern portions of the county.
Due to redistricting, the 75th district has been moved around different parts of the state. The current iteration resulted from the 2021 redistricting by the California Citizens Redistricting Commission.
