Lake Wanapitei (Ojibwe: Waanabidebiing) is an impact crater lake within the city of Greater Sudbury, Ontario, Canada and Wahnapitae First Nation. Adjacent to the nearby but unrelated Sudbury impact crater, it is one of the worlds largest lakes entirely located within the boundary of a single municipality.

The crater itself is 5.2 mi (8.4 km) in diameter, with an estimated age of 37.2 ± 1.2 million years, dating it to the Eocene period. The Anishinaabemowin name for the lake, Waanabidebiing, means "place where the water is shaped like a tooth" and refers to the shape of the lake from above.
