Hamburg, Dan, 1948-

Daniel Hamburg (born October 6, 1948) is an American politician. As a member of the Democratic Party, he notably served in the U.S. House of Representatives from California's 1st congressional district between 1993 and 1995. As a member of the Green Party, he was that party's first candidate for Governor of California in 1998.

Born in St. Louis, Missouri, Hamburg earned a B.A. degree from Stanford University. After graduating, he lived in Ukiah, California, where he founded an alternative school and served on the city planning commission from 1976 to 1981. He also founded a cultural study program in China. Hamburg served on the Mendocino County Board of Supervisors from 1981 to 1985. In 1992, he earned an M.A. from the California Institute for Integral Studies.

In 1992, he was elected to California's 1st congressional district, beating incumbent Frank Riggs. While in Congress, Hamburg was named one of People magazine's "50 Most Beautiful People" in 1993. In 1994, a national backlash against Democrats helped Riggs to defeat Hamburg in a rematch. Hamburg later became a member of the Green Party and ran as the Green Party nominee for California governor in 1998. He was the first Green Party of California candidate for Governor ever, and finished third among seven candidates with 104,117 votes for 1.3% of the total vote. During the 2000 presidential election Hamburg backed Green presidential candidate Ralph Nader.

In November 2010 Hamburg was elected for a second time to the 5th District seat on the Mendocino County Board of Supervisors. Hamburg ran unopposed for reelection in June 2014, and retired from the board in 2018.
