California's 39th congressional district is a congressional district in the U.S. state of California. The district includes parts of Riverside County, including Jurupa Valley, Riverside, Moreno Valley, and Perris. The district has been represented by Democrat Mark Takano ever since he was redistricted from the 41st congressional district in 2022.
Under the 2020 redistricting, California's 39th congressional district was geographically shifted to the Inland Empire in Southern California, specifically within the northwestern region of Riverside County. It includes the cities of Moreno Valley, Jurupa Valley, Perris, and Riverside; and the census-designated places Mead Valley, Home Gardens, Highgrove, March Air Reserve Base, Good Hope, and Meadowbrook.

In January 2018, Republican incumbent Ed Royce announced his retirement. Royce's retirement created great uncertainty and interest in this election, due to the possibility of two candidates of the same political party winning California's jungle primary.
The primary election resulted in two candidates of different parties, with Republican Assemblywoman Young Kim and Democrat Gil Cisneros coming in first and second place respectively. After the general election, it took several days to gather and tally absentee ballots, but on November 17, Cisneros was the projected winner of the election.
The 39th congressional district was originally one of five reapportioned to California after the 1970 United States census.
From 1993 to 2003, the 39th congressional district was a Republican stronghold. In 2003, this territory was mostly redesignated into the neighboring 40th congressional district and 42nd congressional district. From 2003 to 2013, the 39th district was represented by Linda Sánchez, who now represents the 38th congressional district.
