The Playa de Las Teresitas is a beach north of the village of San Andrés municipality of Santa Cruz de Tenerife in Tenerife, Spain.

Originally the beach consisted of mostly rocks and a small strip of black sand. It was divided into three distinct parts that had different names: Tras la Arena which was the original, Los Moros in the middle, and finally the area bounded by the ravine of Las Teresas. In 1973, 270,000 tons of white sand was shipped from Spanish Sahara (now Western Sahara, part of the Sahara Desert) to create an artificial beach of white sand. Two piers and a kilometer long breakwater located 150 meters from the beach was constructed to prevent waves from carrying the sand out to the sea. The project cost 50 million pesetas and an addition 400 million pesetas in 1998 when another 2,800 tonnes sand from Sahara was added to replenish the sand lost in the beach's 25 first years of existence.

It is one of the most popular beaches of the Canary Islands, and is one of the few on Tenerife that do not have the black, volcanic sand that most of the rest of the Canary Islands have. Others such as Las Vistas, in Los Cristianos, are artificial, but the beach at El Médano (the Dune) is entirely natural.
