2004 California State Senate election

The 2004 California State Senate elections were held on November 2, 2004. Senate seats of odd-numbered districts were up for election. Senate terms are staggered so that half the membership is elected every two years. Senators serve four-year terms and are limited to two terms. As was expected, the Democratic Party held on to the majority of the seats.
