Pinus culminicola, commonly known as Potosi pinyon, is a pine in the pinyon pine group, native and endemic to northeast Mexico. The range is highly localised, confined to a small area of high summits in the northern Sierra Madre Oriental in Coahuila and Nuevo León, and only abundant on the highest peak, Cerro Potosí (3713 m). It occurs at very high altitudes, from 3000-3700 m, in cool, moist subalpine climate conditions.
