Harris Newmark (July 5, 1834 – 1916) was a Jewish American businessman, philanthropist, and historian. Newmark immigrated to the United States in 1853. He sailed from Europe to New York City, and then to San Francisco. He joined his older brother and other family in Los Angeles. His branch of the family were among the founders and developers of the region, founding Montebello, California and the related area. Newmark contributed to developing many local institutions, such as the Los Angeles County Library and others supporting children's welfare. He wrote a memoir, Sixty Years in Southern California: 1853–1913, which has been cited in dozens of academic papers and books. It is described as the Los Angeles equivalent of a Pepys diary.
