This lake is located about 260 kilometers southwest of Kuujjuaq, Quebec.

Having a complex shape, this lake contains two main areas, that are joined together by means of a fast.

Originating from the Inuit language, the place name "Nedlouc" signifies "calves" or "the thigh above the knee."

In 1951, the "Commission de géographie du Québec" (Quebec Geographic Board) formalized the name "Lake Nedluc".

The spelling "Nedluk" has been used in history to designate this lake; the latter appears on the Ungava district card in the Ninth Report of the Geographical Board of Canada prepared by James White (1911) [1] The place name Nedlouc River was formalized on December 5, 1968 to the Commission de toponymie du Québec (Quebec Names Board).
