Zanzibar  is a semi-autonomous part of Tanzania in East Africa. It is composed of the Zanzibar Archipelago in the Indian Ocean, 25–50 kilometers (16–31 mi) off the coast of the mainland, and consists of many small islands and two large ones: Unguja (the main island, referred to informally as Zanzibar) and Pemba. The capital is Zanzibar City, located on the island of Unguja. Its historic center is Stone Town, which is a World Heritage Site.

The name Zanzibar is derived from the Persian zang-bâr signifying "black coast".

Zanzibar is inhabited mostly by ethnic Swahili, a Bantu population. There are also a number of Arabs as well as some Indians.

Zanzibaris speak Swahili, a Bantu language that is extensively spoken in the African Great Lakes region. Swahili is the de facto national and official language of Tanzania. Many local residents also speak French and/or Italian.
