Biloxi Wildlife Management Area also referred to as Biloxi WMA, is a 35,644-acre (14,425 ha)[1] privately owned tract of protected marsh land located in St. Bernard Parish, Louisiana, managed by the Louisiana Department of Wildlife and Fisheries (LDWF).

The company retains the exclusive right to conduct mineral exploration as well as other business interests on the property.

[1] The WMA is located approximately 40 miles (64 km) east of New Orleans, north of the Mississippi River–Gulf Outlet Canal (MRGO), that was closed to commercial shipping traffic after surge amplification during Hurricane Katrina, on the east shore of Lake Borgne, in northeastern Saint Bernard Parish.

[4] The Biloxi Wildlife Management Area lies in a region that is vulnerable to coastal erosion, and the marsh offers valuable ecosystem services such as storm-surge mitigation for settlements such as New Orleans, and high-tide shelter for small mammals.

In July 2023, the Coastal Protection and Restoration Authority completed a project nearby, titled Biloxi Marsh Living Shoreline, consisting of concrete units designed to attenuate wave energy and to foster commercially viable oyster reefs along 11 miles (18 km) of shoreline.
