The Lake of the Woods (French: le lac des Bois) is a lake occupying parts of the provinces of Ontario and Manitoba and part of the state of Minnesota. It separates some land in Minnesota from the rest of the United States so that it can be reached from the rest of Minnesota only by crossing the lake or going through Canada. That part of Minnesota is the northernmost part of the U.S. outside Alaska and is known as the Northwest Angle.

The Lake of the Woods is fed by the Rainy River, Shoal Lake, Kakagi Lake and other smaller rivers. The lake is drained by the Winnipeg River into Lake Winnipeg.
