Zanzibar is the semi-autonomous part of Tanzania in East Africa. It is composed of the Zanzibar Archipelago in the Indian Ocean, 25–50 kilometres (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.

There is no eVisa specifically for Zanzibar, but nationals of many countries can obtain a Tanzania eVisa. This permits the holder to visit all parts of Tanzania, including Zanzibar. The eVisa, or electronic visa, is designed to improve security and facilitate entry to the country.
