Lacs des Loups Marins is a lake in the north of the province of Quebec in Canada.

It is located about 150 km east of Hudson Bay and about 20 km northeast of Lac à l'Eau Claire.

The name comes from its population of harbour seals (fr: loups marins or phoques).

They belong to Phoca vitulina mellonae, the only seal subtype in Canada that lives year-round in fresh water.

It was named after the Ungava seals that live on the shores and in the lake.
