Lake Nebagamon is a village in Douglas County, Wisconsin, United States. The population was 1,123 at the 2020 census, up from 1,069 at the 2010 census.

U.S. Highway 2, U.S. Highway 53, and Wisconsin Highway 27 are located in the Lake Nebagamon area. County Road F, County Road P, and County Road B are three of the main routes in the community.

Nebagamon is derived from the Chippewa Indian phrase "Nee-bay-go-moh-win", translated as "place to hunt deer by fire on the water." However, the journals and maps of French explorer Joseph Nicollet suggest that this could be a mistake in translation. It is chronicled on Wednesday, August 9, 1837, by Nicollet, that Nibegomowin Creek (Now Nebagamon Creek, sharing its name with the lake) was, at the time, referred to as Sleeping Bear River. Nibegomowin more closely translates to night-time game waiting and could be a place where games, such as bears, are rested or tracked at night. Sleeping Bear River (Nebagamon Creek) can be seen on Nicollet’s 1843 map, Hydrographical Basin of the Upper Mississippi River.
