Gavin Christopher Newsom (born October 10, 1967) is the current mayor of San Francisco. A Democrat, Newsom was elected mayor in 2003, succeeding Willie Brown and becoming San Francisco's youngest mayor in 100 years. Newsom was re-elected in 2007 with 72 percent of the vote.

Newsom graduated from Redwood High School in Larkspur, California in 1985, and in 1989 from Santa Clara University with a Bachelor of Arts in political science. His PlumpJack Wine Shop, founded in 1992, grew into a multi-million dollar enterprise. He was first appointed by Willie Brown to serve on San Francisco's Parking and Traffic Commission in 1996, and was appointed the following year as Supervisor. Newsom drew voter attention with his Care Not Cash program, designed to move homeless people into city assisted care. He defeated the Green Party's Matt Gonzalez 53% to 47% in a run-off in his race for mayor in 2003, becoming the youngest mayor in San Francisco history.

Newsom has officially announced his candidacy for governor of California in the 2010 election.
