Nyanza Province (Kenyan English pronunciation: [ˈɲaːnzə]; Swahili: Mkoa wa Nyanza), was one of Kenya's eight administrative provinces before the formation of the 47 counties under the 2010 constitution. The region is located in the southwest part of Kenya around Lake Victoria, includes part of the eastern edge of Lake Victoria and is inhabited predominantly by the Luo. There are also Bantu-speaking tribes such as the Gusii, the Kuria and a few traces of the Luhya living in the province. The province derives its name from Nyanza, a Bantu word which means a large mass of water.
