The Coast Douglas Fir or Coast Douglas-fir, Pseudotsuga menziesii var. menziesii, is an evergreen conifer variety of Douglas Fir (Pseudotsuga menziesii) native to western North America, from central California north through Oregon and Washington to British Columbia, Canada. In California, it is found in the Klamath Mountains and the Cascade Range, the California Coast Ranges as far south as the Santa Lucia Mountains in San Luis Obispo County, the Sierra Nevada as far south as the Yosemite region, and a southernmost small stand in the Purisima Hills of Santa Barbara County.

In California the Coast Douglas Fir variety and species Douglas Fir (Pseudotsuga menziesii) occur from near sea level along the coast to 5,900 feet (1800 m) in the Sierra Nevada. Eastward they are replaced by the variety named Rocky Mountain Douglas Fir (Pseudotsuga menziesii var. glauca). The variety named Mexican Douglas Fir (Pseudotsuga menziesii var. lindleyana) is endemic to central and northern montane Mexico.

Coast Douglas Fir trees are not frequently planted in residential gardens, they get very large and need to be provided with substantial space to grow. Douglas Firs are the second-tallest conifer species in the world after Coast Redwoods (Sequoia sempervirens). Trees 200-250 feet (60-75 meters) in height and trunks 5-6.6 feet (1.5-2 m) in diameter are common in old growth forests. Coast Douglas Fir commonly lives more than 500 years and occasionally more than 1,000 years.
