California's 65th State Assembly district is one of 80 California State Assembly districts.

It is currently represented by Democrat Mike Gipson and was previously represented by Sharon Quirk-Silva of Fullerton.

Up until the 2022 election, the district encompassed parts of north Orange County, anchored by the city of Fullerton.

The primarily suburban district was ethnically and socioeconomically diverse.

Due to redistricting, the 65th district has been moved around different parts of the state.
