Nyanza Province of Kenya, is one of Kenya's eight administrative provinces. It is located in the southwest part of Kenya around Lake Victoria. Nyanza 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.
The provincial capital is Kisumu, the third largest city in Kenya. The climate is tropical humid.
The predominant language in Nyanza is Dholuo, a Nilotic language whose origins are from Southern Sudan, spoken by the Luo. Other languages include Gusii, Luhya, Kuria, Suba and the national languages English and Swahili. Other languages from the many Kenyan communities are also spoken in small pockets by migrants from these communities.
