John Chupco (ca. 1821–1881) was a leader of the Hvteyievike, or Newcomer, Band of the Seminole during the time of their forced relocation to Indian Territory. They were the last group to move from Florida to Indian Territory.From 1861 to 1866, Chupco served as chief of the Seminole who supported the Union; they removed to Kansas for safety. There was great bitterness when the tribe divided over their loyalties during the war, with many supporting the Confederacy.
