California's 34th State Assembly district is one of 80 California State Assembly districts.

It is currently represented by Republican Tom Lackey of Palmdale.

The district encompasses the majority of rural San Bernardino County outside of the urban core around the San Bernardino foothills and the Victor Valley.

It stretches across to include small portions of Kern County, including Mojave and California City, and finally stretches down to take in about half of Lancaster and Palmdale in Los Angeles County.

Due to redistricting, the 34th district has been moved around different parts of the state.
