Ruth Peak is a glaciated mountain summit located within Olympic National Park in Clallam County of Washington state. Ruth Peak is the third-highest peak in the Bailey Range, which is a subrange of the Olympic Mountains. Its nearest higher neighbor is Mount Carrie, to the northwest, and Mount Fairchild is set to the north. In clear weather, the mountain can be seen from the visitor center at Hurricane Ridge. Precipitation runoff from the mountain drains into tributaries of the Hoh and Elwha Rivers. The first ascent of this peak was made in 1961 by Bert Brown, Roy Etten, and Victor Nelson.
