The Fort Walton culture is the term used by archaeologists for a late prehistoric Native American archaeological culture that flourished in southeastern North America from approximately 1200~1500 CE and is associated with the historic Apalachee people.

The Fort Walton Mound (8OK6) is an archaeological site located in present-day Fort Walton Beach, Florida, United States. The large platform mound was built about 850 CE by the Pensacola culture, a local form of the Mississippian culture. Because of its significance, the mound was designated a National Historic Landmark in 1964.
