The Wekiva River (sometimes spelled Wekiwa, a Creek word meaning spring of water) is a 16.0-mile-long (25.7 km) river in Central Florida, north of Orlando in the United States. It originates in Apopka, Florida and joins the St. Johns River, the longest river in the state, in DeBary, Florida. The Wekiva River system includes the main stem of the Wekiva River joined by three main tributaries - Rock Springs Run, Blackwater Creek and Little Wekiva River - and about 30 contributing groundwater springs. It is designated as a Florida State Canoe Trail, an Outstanding Florida Water and an Aquatic Preserve by the Florida Department of Environmental Protection.
