Manantiales is a resort (balneario) in the Maldonado Department of southeastern Uruguay.

In the Spanish language in the Americas, a manantial means spring.

The resort is located on the coast of the Atlantic Ocean, on Route 10, between its junction with Route 104 to the east and Laguna Blanca (which means White Lagoon) to the west.

On its coastline is a small point called Punta Piedras.

To the west, it borders a neighbourhood called "Barrio San Carlos",[1] which lies just east of the resort La Barra, and to the east it borders the resort El Chorro.
