Zanzibar is the name of an archipelago in the Indian Ocean 25–50 km off the coast of East Africa. There are many small islands and two large ones: Unguja (the main island, sometimes informally referred to as 'Zanzibar') and Pemba Island.

The archipelago was once the separate state of Zanzibar, which united with Tanganyika to form Tanzania (derived from the two names). Zanzibar is a semi-autonomous within the union, with its own government.
