The Northern Oregon Coast Range is the northern section of the Oregon Coast Range, in the Pacific Coast Ranges physiographic region, located in the northwest portion of the state of Oregon, United States. This section of the mountain range, part of the Pacific Coast Ranges, contains peaks as high as 3,710 feet (1,131 m) for Rogers Peak. Forests in these mountains are considered to be some of the most productive timber land in the world. The Central Oregon Coast Range is directly south of this section with the Southern Oregon Coast Range beyond the central range.

The Tillamook State Forest is a 364,000-acre (1,470 km2) publicly owned forest in the U.S. state of Oregon. Managed by the Oregon Department of Forestry, it is located 40 miles (64 km) west of Portland in the Northern Oregon Coast Range, and spans Washington, Tillamook, Yamhill, and Clatsop counties. The forest receives large amounts of precipitation and is dominated by Douglas-fir trees. Activities include commercial logging, recreation, and other commercial resource extraction activities such as mushroom hunting.
