Lake Winder is a 1,496-acre (6 km²) lake in Brevard County and a small portion lies in Osceola County. The lake was named after U.S. Army Captain Edward Winder. Early in 1838 Winder was assigned to scout the area for Seminoles. He discovered Lake Poinsett. The smaller lake to the south was named after Winder. Lake Winder is the only lake in the St. Johns River basin that doesn't support a marina. The nearest unincorporated settlement is Viera, Florida, 7.3 miles (11.7 km) to the east. It's the third largest lake in Brevard County.
