Bussa, also known as Boussa in older texts, was one of the main cities and kingdoms of the Borgu federation in northern Nigeria. It was the farthest navigable point on the Niger River from the coast, just above the rapids. The town site is now covered by Lake Kainji, which was created in 1968 with the construction of the Lake Kainji dam. The town was re-located to what is now called New Bussa.
