Mount Walkinshaw is a mountain summit located in the Olympic Mountains, in Jefferson County of Washington state. It is situated within Olympic National Park, and is the northernmost peak in The Needles range, which is a subset of the Olympic range. Its nearest higher peak is Mount Clark, to the south, and Gray Wolf Ridge arcs to the northeast. Mount Walkinshaw is set in the eastern portion of the Olympic Mountains within the drainage basin of the Dungeness River. This position puts it in the rain shadow of the Olympic Range, resulting in less precipitation than Mount Olympus and the western Olympics receive.
