Located in south-central Louisiana, Atchafalaya Basin is a combination of wetlands and river delta areas where the Atchafalaya River and the Gulf of Mexico converge. The river stretches from near Simmesport in the north through parts of eight parishes to the Morgan City southern area.

The basin contains about 70% forest habitat and about 30% marsh and open water. It contains the largest contiguous block of forested wetlands remaining (about 35%) in the lower Mississippi River valley and the largest block of floodplain forest in the United States. Best known for its iconic cypress-tupelo swamps, at 260,000 acres (110,000 ha), this block of forest represents the largest remaining contiguous tract of coastal cypress in the United States.

The Atchafalaya Basin has a long relationship with the Mississippi River throughout the Holocene epoch, and the geology of the modern basin is a direct manifestation of that relationship. The Atchafalaya Basin has been part of three historic depositional lobes (Sale-Cypremort, Teche, and Lafourche lobes) of the Mississippi River Delta Plain that formed south Louisiana, and active delta lobe development is currently occurring at the mouth of the Atchafalaya River and Wax Lake Outlet. The geology of the current basin has been driven by flows of Atchafalaya River water and sediment that flowed into open water areas through relict Mississippi River distributary channels.
