The Kingdom of Benin, also known as the Edo Kingdom or Benin Kingdom, is a kingdom within what is now southern Nigeria. It has no historical relation to the modern republic of Benin, which was known as Dahomey from the 17th century until 1975. The Kingdom of Benin's capital was Edo, now known as Benin City in Edo State, Nigeria. The Benin Kingdom was "one of the oldest and most developed states in the coastal hinterland of West Africa". It grew out of the previous Edo Kingdom of Igodomigodo around the 11th century AD, and lasted until it was annexed by the British Empire in 1897.

Benin, officially the Republic of Benin, and also known as Dahomey, is a country in West Africa.

The capital is Porto-Novo, and the seat of government is in Cotonou, the most populous city and economic capital.
