Red Jacket, or Sa-go-ye-wat-ha (1756?–1830), a Seneca Indian orator and chief. He was called Red Jacket because of his fondness for the uniform coats given him by British officers. He joined the British side reluctantly in the American Revolution and was denounced as a coward by Cornplanter for retreating from the fight at Canandaigua against General John Sullivan's expedition. However, Red Jacket opposed peace at the council of confederated tribes at the mouth of the Detroit River in 1786.

In 1792 Red Jacket was one of a group who visited President Washington at Philadelphia, and received a medal which he always wore with great pride. He upheld the traditions of his people and opposed all white influences. When New York passed a law forbidding whites to live on Indian lands, Red Jacket succeeded in ousting a missionary. He was deposed as chief in 1827 because of his conservatism.
