California's 8th State Senate district is one of 40 California State Senate districts.

It is currently represented by Angelique Ashby of Sacramento.

The district is located in the core of the Sacramento metropolitan area, consisting of the state capital of Sacramento and several of its surrounding suburbs, including Rio Linda, McClellan Park, North Highlands, Vineyard, Rosemont, Florin, and Elk Grove.

Due to redistricting, the 8th district has been moved around different parts of the state.

The current iteration resulted from the 2011 redistricting by the California Citizens Redistricting Commission.
