Twin Rivers State Forest, Protected forest area in northern Florida, United States.

Twin Rivers State Forest covers 14,882 acres (60 km²) in North Central Florida, made up of 15 noncontiguous tracts along the Withlacoochee and Suwannee rivers. The Ellaville Tract is the only segment shared by both rivers, lying across from Suwannee River State Park. Other tracts include Mill Creek South, North, Anderson Springs, Black, Damascus, Nekoosa, Withlacoochee, Blue Springs Longleaf, Chitty Bend West and East, Hardee Springs, Westwood East and West, Sullivan and Deese.

Twin Rivers State Forest is managed by the Florida Department of Agriculture, which lists it as 15 noncontiguous tracts along the Withlacoochee and Suwannee rivers. The Ellaville Tract, along the southern edge of I-10, is the only segment shared by both rivers and faces Suwannee River State Park across the water. The Withlacoochee Tract lies opposite Madison Blue Spring State Park, and the Blue Springs Longleaf Tract runs along State Road 6 where it overlaps Hamilton CR 143.

The forest's name comes from the Suwannee and Withlacoochee rivers, which meet only along the Ellaville Tract, across from Suwannee River State Park. The 15 tracts are named for former settlements and landowners, such as Ellaville, a town that once stood near the river crossing, and Nekoosa. Visitors today walk, hunt and watch wildlife on these state lands.

The forest can be reached through several entry points along main roads and county routes, with trails that are easy to walk on foot. Wearing comfortable shoes and watching for insects and wildlife are good practices when spending time here.

The forest is made up of 15 separate land parcels positioned where two rivers meet and create different ecological conditions. This layout means the forest is divided into distinct zones, each with its own mix of plants and animals.
