Chief Billy Bowlegs or Billy Bolek (Holata Micco, Halpatter-Micco, Halbutta Micco, and Halpuda Mikko in Seminole, meaning "Alligator Chief") (c. 1810 – 1864) was a leader of the Seminoles in Florida during the Second and Third Seminole Wars against the United States. One of the last Seminole leaders to resist, he eventually moved to Indian Territory (present-day Oklahoma).
