Las Toscas is a resort of the Costa de Oro in the Canelones Department of southern Uruguay.

The resort is located on the 47th km of Ruta Interbalnearia between Atlántida to the west and Parque del Plata to the east.

Today, Las Toscas is merged with Atlántida to the west and Parque del Plata to the east, but in the creation of these locations, during the first decades of the 20th century, it gave the name to the whole zone.

It was at Las Toscas where the laborious task, developed by various private societies, of foresting the coast of the Río de la Plata began.

The success of this task is because of Mario Ferreira, whose name is taken by the main street of the resort.
