The Saturiwa were a Timucua chiefdom centered on the mouth of the St. Johns River in what is now Jacksonville, Florida. They were the largest and best attested chiefdom of the Timucua subgroup known as the Mocama, who spoke the Mocama dialect of Timucuan and lived in the coastal areas of present-day northern Florida and southeastern Georgia. They were a prominent political force in the early days of European settlement in Florida, forging friendly relations with the French Huguenot settlers at Fort Caroline in 1564 and later becoming heavily involved in the Spanish mission system.
