Toponymy
This hydronym evokes the work of life of the surveyor Paul Malouin (1884–1945), born in Quebec City. The latter undertook studies at the School of Surveying at Laval University in 1904. Received surveyor-surveyor in 1910, he joined the same year with the surveyor Paul Joncas under the enterprise name "Joncas and Malouin".

The designation "Malouin River" is indicated on a regional map of the Abitibi of the Department of Lands and Forests in 1962. In 1895, explorer Henry O'Sullivan named this watercourse "Rivière du Mariage" (English: The River of Marriage) or "Birthday", having discovered him on September 15, 20th anniversary day of his marriage.

The hydronym "Malouin River" was formalized on December 5, 1968, by the Commission de toponymie du Québec, i.e. at the creation of this commission.
