MacNaughton Mountain is a mountain located in Essex County, New York, named after James MacNaughton (1851–1905), the grandson of Archibald McIntyre. The mountain is part of the of the Adirondack Mountains. MacNaughton Mountain is within the High Peaks Wilderness Area of New York's Adirondack Park. Because it is not one of the officially recognized Adirondack High Peaks and it does not offer notable views, MacNaughton is not climbed as frequently as many other mountains. There is no maintained trail or clear herd path for most of the climb from the end of the nearest trail at Wallface Pond.
