Greenleaf Lake State Recreation Area is a state park unit of Minnesota, USA, currently in development. It includes undeveloped shoreline on both Greenleaf and Sioux Lakes, halfway between the cities of Hutchinson and Litchfield in Meeker County. Portions of the state recreation area (SRA) are open to the public for day-use recreation, but there are no facilities yet on site. The park boundaries were set by the Minnesota Legislature and the state is still acquiring land from willing sellers; two-thirds of the property remain privately owned.
