The KwaZulu-Natal Sharks Board, previously the Natal Sharks Board and Natal Anti-Shark Measures Board is an organisation that maintains shark nets and drum lines off the coast of KwaZulu-Natal Province, South Africa, to protect bathers and surfers from shark attacks, at 38 places, along 320 km of coastline. It was founded as a statutory body in 1962, when the city of Durban's netting operations were extended to other parts of the coast in the then Natal Province. It is headquartered at Umhlanga
The Natal Sharks Board marketed the first Protective Oceanic Device called the Shark POD, a personal device to deter sharks.
