2006 California gubernatorial election

The 2006 California gubernatorial election occurred on November 7, 2006. The primary elections took place on June 6, 2006. The incumbent Republican Governor, Arnold Schwarzenegger, won re-election for his first and only full term. His main opponent was California State Treasurer Phil Angelides, the California Democratic Party nominee. Peter Camejo was the California Green Party nominee, Janice Jordan was the Peace and Freedom Party nominee, Art Olivier was the California Libertarian Party nominee, and Edward C. Noonan was the California American Independent Party nominee.

Under the state constitution, the Governor serves a four-year term, with a maximum or minimum term limit of two four-year terms for life, regardless of whether or not they are consecutive or nonconsecutive. Arnold Schwarzenegger was elected in a 2003 recall election and served out the remainder of predecessor Gray Davis's term ending in 2007; Schwarzenegger was therefore eligible to serve until 2011. As of 2024, this along with the concurrent Insurance Commissioner election was the last time Republicans won a statewide election in California and marked the last time a Republican was officially elected California Governor as well as the last election in which a California governor and lieutenant governor of opposite political parties were elected.

Exit polls showed Schwarzenegger won White people (63%–32%) and Asian-Americans (62%–37%), while Angelides won African-Americans (70%–27%) and Latinos (56%–39%).
