Bishop pine occurs in disjunct populations in coastal California from Humboldt County south to Santa Barbara County. It is also found on Santa Cruz and Santa Rosa islands, and in Baja California, Mexico .

Bishop pine is frequently dominant in closed-cone pine forests . Stands are open with little or no understory on dry, rocky sites, with a more dense understory on moist sites . Bishop pine also occurs in mesic border areas of woodlands and savannas .
