The Kingdom of Bonny, otherwise known as Grand Bonny, is a traditional state based on the town of Bonny in Rivers State, Nigeria. In the pre-colonial period, it was an important slave trading port, later trading palm oil products. During the 19th century the British became increasingly involved in the internal affairs of the kingdom, in 1886 assuming control under a protectorate treaty. Today the King of Bonny has a largely ceremonial role.

Bonny is a traditional, coastal town and a Local Government Area (LGA) in Rivers State in Southern Nigeria, on the Bight of Bonny. It is also the capital of the Kingdom of Bonny.
