Image Lake is a tarn in Glacier Peak Wilderness, in the North Cascades of Washington, United States. The lake is surrounded by Plummer Peak to the east, a lookout point to the west, the Miners Creek drainage and Glacier Peak to the south, and Canyon Lake to the north. The course of the popular Miners Ridge Trail skirts the lake. Glacier Peak can be seen from the outlet of the lake, and the peak reflected in the lake is a popular photographic subject.

Glacier Peak Wilderness is a 566,057-acre (229,075 ha), 35-mile-long (56 km), 20-mile-wide (32 km) wilderness area located within portions of Chelan, Snohomish, and Skagit counties in the North Cascades of Washington. The area lies within parts of Wenatchee National Forest and Mount Baker National Forest and is characterized by heavily forested stream courses, steep-sided valleys, and dramatic glacier-crowned peaks. The dominant geologic feature of the area is 10,541-foot (3,213 m) Glacier Peak. It is the most remote major volcanic peak in the Cascade Range and has more active glaciers than any other place in the lower forty-eight states. Glacier Peak is a volcanic cone of basalt, pumice, and ash which erupted during periods of heavy glaciation.
