John Philip Clum (September 1, 1851 - May 2, 1932) was an Indian agent for the San Carlos Apache Indian Reservation in the Arizona Territory. He implemented a limited form of self-government on the reservation that was so successful that other reservations were closed and their residents moved to San Carlos. Clum later became the first mayor of Tombstone, Arizona Territory, after its incorporation in 1881. He also founded the still-operating The Tombstone Epitaph on May 1, 1880. He later served in various postal service positions across the United States.
