The Mark O. Hatfield Wilderness is a wilderness area located on the northern side of Mount Hood in the northwestern Cascades of the U.S. state of Oregon, near the Columbia River Gorge and within Mount Hood National Forest. Prior to Wilderness designation it was known as the Columbia Gorge Recreation Area.

The slopes of the Wilderness rise steeply to a slightly uneven plateau and on to mountain peaks, talus slopes, and lakes with elevations ranging from approximately 100 feet (30 m) near the river to 4,900 feet (1,500 m) on Mount Defiance. The main waterways in the Wilderness are Herman Creek, Eagle Creek, and Tanner Creek.^[1]
