Tanga Island[1] known during German East Africa as Toten Island in old colonial maps (Swahili Toten, adapted from German Toteninsel, meaning "Island of the Dead") is a small uninhabited and protected island situated north of the city of Tanga's harbour on Tanga Bay in Tanga Region, Tanzania.

The island is located entirely with the Tanga Coelacanth Marine Park (TCMP).

[2] [3] The island is a historical site that contains ruins of two Medieval Swahili mosques and tombs.

[4] The current name comes from the German word for "dead bodies" alluding to the numerous graves on the island.

In 1884 the remaining people moved to what is present day Tanga city.
