Apalachee Province was the area in the Panhandle of the present-day U.S. state of Florida inhabited by the Native American peoples known as the Apalachee at the time of European contact. The southernmost extent of the Mississippian culture, the Apalachee lived in what is now Leon County, Wakulla County and Jefferson County. The name was in use during the early period of European exploration. During Spanish colonization, the Apalachee Province became as one of the four major provinces in the Spanish mission system, the others being the Timucua Province, (between the St. Johns and Suwanee Rivers), the Mocama Province (along the Atlantic coast of what is now northern Florida and southern Georgia) and the Guale Province (along the Georgia coast north of the Altamaha River).
