Sideroxylon socorrense is a plant species in the family Sapotaceae. It is endemic to Mexico, occurring only on Socorro in[1] the Revillagigedo Islands.[2]

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.[3] 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)[4] and the Socorro dove (Zenaida graysoni) which presently only survives in captivity.[5] Similar as in other Sideroxylon, these birds might be crucial for the present species' reproduction.
