The name comes from the Forbord hamlet located west of the mountain, and the name Forbord supposedly means at the foot of the mountain. Thus, the name Forbordsfjellet can, oddly enough, be translated into at the foot of the mountain-mountain. The solution to this logical problem may be that the hamlet at the foot of the mountain may have been named Forbord first, but when the locals forgot the name of the name, the mountain was given the name Forbordsfjellet. There are no other known names on the mountain.
