Waterproof is a village in Tensas Parish in northeastern Louisiana, United States with a population of 834 as of the 2000 census. However, the population declined in the 2010 census by 17.5 percent to 688. The village in 2010 was 91.7 percent African American. Some 24 percent of Waterproof residents in 2010 were aged sixty or above.
Waterproof is approximately 17 mi (27 km) north of Ferriday, one of the two principal communities of Concordia Parish. The village is named for its relative safety from flooding prior to construction of the Mississippi River levee system.
With a population dependent on agriculture, the rural village struggles with poverty. Mechanization has decreased the need for farm labor. Industrial-scale cotton is the major commodity crop, but corn and soybeans are also important. In 2008, drought destroyed much of the corn crop.
The former Hunter's Brothers Store, once a mainstay of Waterproof, is featured in an article in the first volume of the publication North Louisiana History.
