Uzi Island is an island in the south of Zanzibar, connected by a causeway to the main island of Unguja. It is located immediately to the south of the main island’s Unguja Ukuu ruins.
The island is undeveloped and contains few occupants who temporarily dwell there for fishing. Uzi Island is six kilometres (3.7 miles) in length, making it the second-largest of the smaller islands which surround Unguja (after Tumbatu in the north).
