The Kingdom of Niumi, also known as the Kingdom of Barra, was a West African nation at the Gambia River. Niumi was located at the mouth of the river, and extended nearly 60 kilometres (40 mi) along and north of its north bank. For much of its existence, its eastern border was occupied by the Kingdom of Baddibu, and its northern border was open savanna leading to Senegal. Formally becoming part of the Gambia Colony and Protectorate in 1897, the Kingdom now forms the Upper Niumi and Lower Niumi districts of the North Bank Division in The Gambia.
