The United States House of Representatives elections in California, 1998 was an election for California's delegation to the United States House of Representatives, which occurred as part of the general election of the House of Representatives on November 3, 1998. Democrats gained the 1st district but lost the 3rd and 36th (which they would gain back in 2000) districts for a net loss of one seat.
This was the last time until a special election in 2020 where a Republican flipped a Democratic-held U.S. House seat in California, and also the last time until 2020 that Republicans flipped a Democratic-held seat in a general election.
Three special elections were held apart from those in November. The elected winners would serve the remainder of the incumbent Congress and face re-election in November.
