Corumbau Marine Extractive Reserve is a coastal marine extractive reserve in the state of Bahia, Brazil. The reserve was created in 2000 to help protect the traditional local fishing economy, which was suffering from predatory commercial fisheries. It includes an area of corals and rich marine biodiversity, and a breeding ground for humpback whales. Growth in tourism has caused a surge in real estate prices and introduced new social problems among the traditional residents.

An extractive reserve is a type of sustainable use protected area in Brazil. The land is publicly owned, but the people who live there have the right to traditional extractive practices, such as hunting, fishing and harvesting wild plants.
