Charles Boxton (April 24, 1860 in Shasta County, California – August 29, 1927 in San Mateo, California) served as the 27th mayor of San Francisco from July 9 to July 16, 1907.
He attended the San Francisco public schools and then entered a dental apprenticeship. Afterwards he entered the University of California, where he earned a D.D.S. degree, and then entered private practice in San Francisco.
He soon left his dental practice to fight in the Philippine–American War. After returning home, he entered politics and was elected to the San Francisco Board of Supervisors in 1899. He also became dean of the Dental Department at the College of Physicians and Surgeons.
After the corruption trial of mayor Eugene Schmitz, the Board of Supervisors chose him to serve out Schmitz's remaining term. However, during the trial, it was revealed that Boxton had taken bribes and he was forced to resign after only a week in office. He then resumed his dentistry practice.
