John Horse (c. 1812–1882), also known as Juan Caballo, Juan Cavallo, John Cowaya (with spelling variations) and Gopher John, was of mixed ancestry (African and Seminole Indian) who fought alongside the Seminoles in the Second Seminole War in Florida. He rose to prominence in the third year of what was to become a seven-year war when the first generation of Black Seminole leaders was largely decimated and the primary Seminole war chief, Osceola (Asi Yahola), fell into the hands of the American military commander, General Thomas Sydney Jesup.
