Fred Gannon Rocky Bayou State Park, State park in Niceville, United States.

Fred Gannon Rocky Bayou State Park is a Florida state park at 4281 Highway 20, southeast of Niceville in Okaloosa County.

During World War II, this land was used as a bombing practice range connected to the nearby Eglin Air Force Base. After the war, Colonel Fred Gannon led efforts to protect the site, and it was formally designated as a state park in 1966.
