The Islas San Benito lie in the Pacific Ocean off the west coast of the Mexican state of Baja California, 25 km west of Cedros Island. They are part of the Cedros Island delegación, a subdivision of Ensenada (municipality), Baja California.
The group consists of three barren islands, with a total area of 3.899 km2, and is surrounded by rocks and patches of kelp. The census of 2001 recorded a population of two on Benito del Oeste (West Benito); the other islands are uninhabited.[1]
