Lone Mountain Cemetery was a complex of cemeteries in the Lone Mountain neighborhood of San Francisco, California on the land bounded by the present-day California Street, Geary Boulevard, Parker Avenue, and Presidio Avenue. Opened 1854, it eventually comprised Laurel Hill Cemetery, Calvary Cemetery, the Masonic Cemetery, and Odd Fellows Cemetery. Pressure to close the complex began around the beginning of the twentieth century, and by 1941 all remains within it had been moved elsewhere, mostly to a new necropolis in Colma, California, though some were never accounted for.
