The Mountain Longleaf National Wildlife Refuge is a natural area in Anniston, Alabama. It features the former site of the historic Fort McClellan, which dates back to the days of the Spanish-American War.

Established in 2003, the Mountain Longleaf National Wildlife Refuge is a relatively new venue of such kind in the South. It was named after the area, which has some of the last surviving mountain longleaf pine forests in the region. It features about 3000 acres of land area, although 6000 acres more is in the process of inclusion. The area is still in a process of completion, so there will definitely be more information about the site in the future. It is open year round, during daylight hours.
