Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California. It is notable for having the largest (by far) cones in the genus Pseudotsuga, hence the name.

The tree occurs from the San Rafael Mountains in central Santa Barbara County and the Tehachapi Mountains of southwestern Kern County, south through the Transverse Ranges, to the Cuyamaca Mountains in San Diego County. The tree is shade-tolerant and prefers to grow on slopes.
