Lac La Belle (French: "beautiful lake"), is the name given to both a lake and a small unincorporated community in Keweenaw County in the U.S. state of Michigan. The town was originally the site of a stamping plant for the coppermines of the Keweenaw, specifically the Mendota Mine and the Delaware Mine. Copper-bearing rock was transported from the mines to the stamping plant, where it was processed and loaded onto freighters. The lake is a typical "Canadian Shield" type lake averaging approximately 30 feet (9 m) deep, and empties into Lake Superior at Bete Gris, by way of both a natural channel and a dredged canal. The canal was dredged in the 1860s with funding from several copper mining companies, for use by lake freighters, carrying copper ore.
The Little Gratiot River and several creeks, empty into Lac La Belle. A small roadside park within the town contains Haven Falls on Haven Creek, which also empties into the lake.
Lac La Belle has an active summer tourist industry, with many summer cottages and resorts. The area has many dense forests and small mountains. There are backwoods outfitters who guide hikers through these areas. In the winter, the nearby Mount Bohemia attracts skiers and snowboarders.
