|Bay of Diego Suarez|
|Ocean/sea sources||Indian Ocean|
Antsiranana Bay (also known as Diego-Suarez Bay) is a natural bay that stretches close to 20 kilometres (12 mi) north to south along the northeast coast of Madagascar. The waters average a depth of more than 20 metres (66 ft), and the main channel can be as deep as 50 metres (160 ft). The bay, protected by a narrow inlet that provides shelter from strong Indian Ocean winds, is believed to be the result of a submerging coastline or a drowned river valley that formed many peninsulas around the bay.
The bay's principal city, Antsiranana, is located on a headland; its port, formerly military, became the second commercial port of the island.
The bay was first recorded by European explorers in 1500; sailors in the service of Prince Henry the Navigator named the bay for their leader, Diogo Diaz. The bay was later used for shelter by a number of pirates and privateers during the Golden Age of Piracy, and it has been speculated as a possible location of the legendary pirate colony Libertalia.
