Blue Lake Peak is the unofficial name of a 7,800+ ft summit in the North Cascades Range in the U.S. state of Washington. It is located in the Okanogan–Wenatchee National Forest on the shared border of Okanogan County and Chelan County. It is situated south of Early Winters Spires, Liberty Bell Mountain, and Washington Pass. Blue Lake is set below its west slope, and Stiletto Peak is to its south. Blue Lake Peak can be seen from the North Cascades Highway at the Blue Lake Trailhead. Precipitation runoff from Blue Lake Peak drains into tributaries of the Chelan River and Methow River.
