Huckleberry Mountain is a mountain summit located on the shared border of King County and Kittitas County in Washington state. It is situated within the Alpine Lakes Wilderness which is part of the Cascade Range. Huckleberry Mountain is set on land managed by Mount Baker-Snoqualmie National Forest. Huckleberry Mountain is northeast of Snoqualmie Pass, and 0.77 mile west of Chikamin Peak, which is also its nearest higher peak. The Pacific Crest Trail traverses the south and east slope of Huckleberry Mountain, and from the trail a class 4 scramble leads to the summit. Precipitation runoff on the east side of the mountain drains into tributaries of the Yakima River, whereas the west side of the peak drains into tributaries of the Snoqualmie River.
