Dry Prong is a village in central Grant Parish, Louisiana, United States. It is part of the Alexandria, Louisiana Metropolitan Statistical Area. The population was 436 at the 2010 census.

Dry Prong was incorporated as a village in 1945.

According to tradition, the village received its name when a family moved to the region in the 1870s to build a sawmill. To power the mill, they built a water wheel, only to discover that the creek over which they had built it went dry every summer: the creek was a "dry prong". The mill was soon rebuilt over a nearby creek which flowed all year, but the name stuck. The creek is now outside the city limits, on Highway 123. Shane Davis is the current mayor of the village.
