San Marcos de Apalache Historic State Park is a Florida State Park in Wakulla County, Florida organized around the historic site of a Spanish colonial fort (known as Fort St. Marks by the English and Americans), which was used by succeeding nations that controlled the area. The Spanish first built wooden buildings and a stockade in the late 17th and early 18th centuries here, which were destroyed by a hurricane.

The stone fort was built beginning in 1753. It came under successive control by Great Britain, Spain, the United States and, lastly, the Confederacy during the American Civil War. A U.S. Marine Hospital was built from the materials of the fort. The US took control of the site again in 1865, and the fort site was abandoned.

On November 13, 1966, the fort area was designated a National Historic Landmark because of its significance and added to the U.S. National Register of Historic Places.^[1][3] Designated as a National Engineering Landmark, the fort site has been highlighted on the Florida Native American Heritage Trail. On October 10, 1962, Congress authorized designating Fort Saint Marks as a National Historic Site^[4] upon donation of the site to the National Park Service. That donation apparently never happened, however, and the site remains a Florida State Park and a National Historic Landmark.

The historic park is located in the vicinity of St. Marks, off S.R. 363, at 148 Old Fort Road.
