Elections were held in California on June 3, 2008. The elections included two ballot propositions and one recall election for a State Senate seat. All primary elections for Californian seats to the House of Representatives, all of the seats of the State Assembly, and all odd-numbered seats of the State Senate were also held.

Proposition 98 would have been a constitutional amendment that limited eminent domain and gradually eliminated rent control.

Proposition 99 was a constitutional amendment that limited eminent domain and government acquisition of owner-occupied residences.

In response to his actions involving the state budget, a petition to recall State Senator Jeff Denham, a Republican who represents California's 12th State Senate district, was circulated. In the election his successor was to be determined, if a majority of voters favored the recall. As it happened, the majority did not and he remained in office.
