Waterproof is a village in Tensas Parish in northeastern Louisiana, United States with a population of 541 as of the 2020 census. 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.

Jim Crow rules were strong through the segregation era, and the Ku Klux Klan was active in southwest Louisiana through the late 20th century. Although there were 7,000 blacks living in the parish in 1964, none had been registered to vote. The 4,000 whites controlled parish and city politics for decades. The first 15 blacks were registered to vote in 1964, after passage of national civil rights legislation.

Three young Waterproof men died in action in the Vietnam War: Carl Raymond Goodfellow, a navy ensign; Robert Lee Ross, an army private; and Douglas Mac Washington, an army sergeant.

As of 1990, Waterproof hosted "a general store, a grocery, two gas stations, two banks and the Western Auto franchise".

The village has the Tensas Parish Detention Center South. This prison facility holds inmates sentenced in Waterproof and Tensas Parish courts and courts of other cities in the Tensas Parish area. It has recently been used to detain undocumented immigrants. The listed address of Tensas Parish Detention Center South is 8606 Highway 65.

On December 8, 2018, the village elected its youngest mayor in history, Jarrod Randell Bottley, an African American male. He was 31 years old at the time and serves the town on a full-time basis.

In September 2006 Bobby D. Higginbotham was elected as mayor of Waterproof. After taking office, he hired Miles Jenkins as chief of police. Both native to Waterproof, the two African-American men had also lived and worked for years in other cities, including New Orleans. Jenkins had a 30-year career in the US military and earned a master's degree in public administration from Troy University in Alabama. He started to professionalize the small town police department.

On July 24, 2007, Parish Sheriff Rickey A. Jones, who is white, arrested Higginbotham on counts of impersonating a police officer, criminal trespass, and felony criminal damage to property. Higginbotham claimed that Jones arrested him in order to prevent his running for sheriff again in the October 20, 2007, non-partisan blanket primary. Jones said he incurred $7,500 in legal fees before he took office as sheriff because Higginbotham sued him over allegations of a "rigged" election. In the 2007 primary, Jones defeated Higginbotham, 2,188 votes (77.6 percent) to 631 votes (22.4 percent).

Jones and District Attorney James E. Paxton of the Louisiana 6th Judicial District, who was elected in 2008, recognized Caldwell A. Flood Jr., as the bona fide mayor of Waterproof. Police chief Miles Perkins was also arrested and charged for profiting from traffic tickets.

In March 2010, Police Chief Miles Jenkins filed a lawsuit asserting conspiracy by Jones, Paxton, and other members of the white power structure to prevent the legal exercise of power by black elected officials. He said that he and Higginbotham were illegally forced from office and prosecuted by white officials. He cited numerous arrests by Jones and prosecution by Paxton, on charges that observers said they had never heard used against a police official. The case was closely watched by civil rights activists.

Although the village is 55% black, Higginbotham was convicted by a jury of 11 whites and one black in 2010 of two charges: malfeasance in office and felony theft. He was sentenced to five years of hard labor, two years suspended, for malfeasance and seven years hard labor, three years suspended, for felony theft. The conviction was reversed and the sentence was vacated by the Second Circuit Court of Appeals in April 2012, based on trial irregularities, including missing witness testimonies. Higginbotham had been freed on parole for good behavior in December 2011. The Louisiana State Supreme Court denied a writ of certiorari. In 2016, the US Court of Appeals, Fifth Circuit, upheld the District Court decision denying habeas relief.
