Four Brothers is a mountain summit located in Kittitas County of Washington state. It is set within the Alpine Lakes Wilderness on land managed by Wenatchee National Forest, which is part of the Cascade Range. Four Brothers is northeast of Snoqualmie Pass, on Chikamin Ridge, southeast of its parent, Chikamin Peak. The Pacific Crest Trail traverses the west slope of Four Brothers, and again on the east side as it crosses the gap between Four Brothers and Three Queens. The mountain was named in the 1890s for brothers John, Tom, Vic, and Lawrie Denny, miners who lived in a cabin at the base of the four peaks. The mountain is within the Yakima River drainage basin. Precipitation runoff from the mountain drains west into headwaters of Gold Creek, or east into Glacier Lake.
