The Camuy River (Spanish: Río Camuy; Spanish pronunciation: [kaˈmuj]) is a river in Puerto Rico. It is the third largest underground river in the world and helped shape the cave system known as the Rio Camuy Caves.
The river and water flow systems of Río Camuy have been studied by the US Geological Service in 1995.
