Milton Marks, Jr. (July 22, 1920 – December 4, 1998) was a California politician who served in the California State Assembly and California State Senate, as both a Republican and a Democrat, representing San Francisco for 38 years.
Born in San Francisco, Marks attended the city's Alamo Grammar School and Galileo High School, where he participated in the Junior Reserve Officers' Training Corps. After graduating from Galileo as valedictorian of the class of 1937, Marks went on to earn an A.B. from Stanford University in 1941, where he had been part of the Army Reserve Officers' Training Corps. Marks went on to the UC Berkeley School of Law and was studying with a friend, future federal judge Milton Lewis Schwartz, at International House Berkeley during the attack on Pearl Harbor. Less than a month after the attack, Marks reported to Fort Ord as a Second Lieutenant in the United States Army. Serving in the Pacific Theater of Operations, including the Philippines Campaign (1944–45), he was the Assistant Defense Counsel for the Court of the Eighth United States Army during the Occupation of Japan. After completing his Army service as a Major, Marks returned to the UC Berkeley Law School but eventually transferred, graduating from San Francisco Law School in 1949.
