Mount McLoughlin is a steep-sided lava cone built on top of a shield volcano in the Cascade Range of southern Oregon and within the Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc. The mountain is north of Mount Shasta, south of Crater Lake, and west of Upper Klamath Lake. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company.
