Eagle is a town in Waukesha County, Wisconsin, United States.

The town's name comes from an 1836 incident when pioneer Thomas Sugden and two companions, exploring the area, spotted what was described as "a monster bald-headed eagle... hovering and curving over a large mound" in the midst of the prairie.

9.9% of all households were made up of individuals, and 3.2% had someone living alone who was 65 years of age or older.

Old World Wisconsin, an open-air museum re-creating the working farmsteads and settlements of European immigrants, is in Eagle.

The museum demonstrates teams of oxen and horses working in the fields, farm folk preparing meals over wood-burning stoves, and heirloom plants in gardens.
