San Benedicto, formerly San Tomás, is the third largest island of the Revillagigedo Islands, located at 19°19′N, 110°49′W.

. It is 4.8 km by 2.4 km in size, with an area 10 km². It is of volcanic origin. It has two prominent peaks. The tallest peak, Bárcena, rises to a height of 310 meters near the southern part of the island. It forms a typical volcanic crater. Barcena's only historic eruption began on August 1, 1952 and continued to about February 24, 1953. The eruption destroyed much of the flora and terrestrial fauna.

San Benedicto Island is a popular scuba diving destination known for underwater encounters with dolphins, sharks, giant manta rays and other pelagics. An area called "The Boiler" is where divers commonly interact with the Giant Pacific Mantas. Divers have also spotted Tiger sharks, Galapagos sharks, Silky sharks, and humpback whales here. Since there is no public airport on the island, divers visit here aboard live-aboard dive vessels such as the 112' Solmar V out of Cabo San Lucas, Mexico. The most popular months are between November and May when the weather and seas are calmer.
