John Hopkin Ashley (March 19, 1888 or 1895 – November 1, 1924) was an American outlaw, bank robber, bootlegger, and occasional pirate active in southern Florida during the 1910s and 1920s. Between 1915 and 1924, the self-styled "King of the Everglades" or "Swamp Bandit" operated from various hideouts in the Florida Everglades. His gang robbed nearly $1 million from at least 40 banks while at the same time hijacking numerous shipments of illegal whiskey being smuggled into the state from the Bahamas. Indeed, Ashley's gang was so effective that rum-running on the Florida coast virtually ceased while the gang was active. His two-man raid on the West End in the Bahamas in 1924 marked the first time in over a century that American pirates had attacked a British Crown colony.
