Charles Edward Sebastian (March 30, 1873 – April 17, 1929) was the 30th mayor of Los Angeles, California, serving from 1915 to 1916.

Originally a patrolman in the LAPD, Sebastian climbed the ranks to Chief of Police and served in that office from January 3, 1911 to July 16, 1915.

According to Thomas Reppetto's The Blue Parade, "In 1915 he resigned to run for mayor but was accused of illicit relations with young ladies.

Sebastian countered by staging a phony attempt on his life, but the plot was revealed and he resigned.

"[1] During his brief mayoralty, Sebastian oversaw the annexation of numerous outlying areas, including most of the San Fernando Valley and the West Side.
