Cupressus pigmaea (Mendocino cypress or pygmy cypress) is a taxon of disputed status in the genus Cupressus endemic to certain coastal terraces and coastal mountain ranges of Mendocino and Sonoma Counties in northwestern California. It is a highly variable tree, and closely related to Cupressus goveniana, enough to sometimes be considered a subspecies of it.
