The Atlantic coastal plain upland longleaf pine woodland is plant community found on the southern Atlantic coastal plain, in the states of southern Virginia, North Carolina, South Carolina, Georgia and northeastern Florida.
These woodlands are dominated by longleaf pine (Pinus palustris) and occur on uplands and on the higher parts of upland-wetland mosaics.
Soils are well- to excessively drained.
The herbaceous layer is dominated by grasses, particularly wiregrass: (Aristida stricta) in the north and (Aristida beyrichiana) in the south.
These woodlands may once have been the most widespread plant community within their range.
