Hinman Glacier was a glacier that flowed to the north and northwest from near the summit of Mount Hinman, in the U.S. state of Washington. Hinman Glacier was within the Alpine Lakes Wilderness of Snoqualmie National Forest. The glacier was approximately 1.3 km2 (320 acres) in 1971, making it the largest glacier between Mount Rainier and Glacier Peak, but an expedition by glaciologists from Nichols College in August 2022 discovered that the glacier had disappeared, with only a few snowfields and non-flowing remnant ice areas totalling 0.04 km2 (9.9 acres) remaining. Smaller glaciers in this part of the Cascade Range preceded the Hinman Glacier in disappearing as part of the retreat of glaciers since 1850 with only three glaciers remaining in King County.
