Star Peak is a mountain summit located in the Methow Mountains, a sub-range of the North Cascades in Washington state. The peak is the highest point on Sawtooth Ridge. It is protected by the Lake Chelan-Sawtooth Wilderness within the Okanogan National Forest. The nearest higher peak is Oval Peak, to the north. Precipitation runoff on the south side of the mountain drains into Lake Chelan via Prince Creek, whereas the north side of the mountain drains into Buttermilk Creek which is a tributary of the Twisp River.
