"Sideroxylon socorrense" is a plant species in the family Sapotaceae. It is endemic to Mexico, occurring only on Socorro in ["And" in WCMC (1998) is an error.] the Revillagigedo Islands [CMICD (2007)] .

On its island home, this small tree grows in habitat that is at least seasonally humid. This restricts it mainly to a belt of woodland between 650 and 900 m above mean sea level, except on the northern side where wetter conditions predominate [Brattstrom, Bayard H. & Howell (1956), WCMC (1998)] . It is classified as Vulnerable by the IUCN due to the adverse effects of introduced sheep grazing and the twice-yearly swarming of the locust "Schistocerca piceifrons", a non-native pest that has become established on Socorro more recently.

The fruits of this plant are among the favorite foods of the nearly-extinct Socorro Mockingbird ("Mimus graysoni") [BLI (2007a)] and the Socorro Dove ("Zenaida graysoni") which presently only survives in captivity [BLI (2007b)] . Similar as in other "Sideroxylon", these birds might be crucial for the present species' reproduction.
