Lake Shetek is the largest lake in southwestern Minnesota, United States, and the headwaters of the Des Moines River. It is located in The Lakes, an unincorporated community in Murray County a few miles north-northwest of Currie. The name Shetek is derived from "pelican" in the Ojibwe language. Since large lakes are rare in southwestern Minnesota and for some distance over the borders into Iowa and South Dakota, Lake Shetek is a significant regional draw for water recreation. Lake Shetek State Park lies on its eastern shore.
