Possumneck is an unincorporated community located in Attala County, Mississippi, United States, along Mississippi Highway 19 and is approximately 4.3 miles (6.9 km) south-southeast of West.

Possumneck is on land that once belonged to the Choctaws until the Treaty of Dancing Rabbit Creek.

A local historian recounted that the name "Possumneck" was derived from a joke about all of the possums that lived in "The Neck", which caused its inhabitants to then refer to the community as Possumneck.

The community once had one of the largest sawmills and cotton gins in Attala County.
