California's 17th State Assembly district is one of 80 California State Assembly districts.

It is currently represented by Democrat Matt Haney of San Francisco.

The district encompasses the eastern portions of the consolidated city-county of San Francisco, including its central financial and governmental core as well as several of the more working-class neighborhoods of the city.

Due to redistricting, the 17th district has been moved around different parts of the state.

The current iteration resulted from the 2021 redistricting by the California Citizens Redistricting Commission.
