# Ndilǫ

Ndilǫ /ˈdiːloʊ/ is a First Nations community in the North Slave Region of the Northwest Territories, Canada. The small Dene community is on the edge of Yellowknife on the tip of Latham Island. It had a population of approximately 321 people in 2016. Ndilǫ and Dettah are the communities of the Yellowknives. Ndilǫ is represented by the Yellowknives Dene First Nation (Ndilǫ) and are part of the Akaitcho Territory Government. The Ndilǫ traditionally speak the Dene dialects Wíílíídeh and Chipewyan (Denesuline).
The land was set aside for use by status Indians by the Government of Canada in 1947 and was called 'Lot 500' on the official register. In 1959, the government built the first ten permanent houses for Dene families. They were colourful homes and so people began referring to the community as 'Rainbow Valley'. In the 1970s there were 200 residents living in 20 houses. The name was officially changed to Ndilǫ in 1991, which means "end of the island" in the local Dene dialect.
The community hosts a public school, the K'àlemì Dene School, a band office and headquarters for Det’on Cho, a First Nations investment company.
