Lake Lillian is a freshwater lake located within the Alpine Lakes Wilderness in a valley on the southern slope of Rampart Ridge in Kittitas County, Washington, United States. Because of its close proximity to Snoqualmie Pass, Interstate 90 and several cirque on both sides of Rampart Ridge, the lake is a common area for hiking, swimming, and fishing rainbow trout. Rocky Run Creek outflows from Lake Lillian into neighboring Lake Laura and continues toward NF road 136 on Rampart Ridge Backdoor. Lake Lillian is between Keechelus Lake on the West and Kachess Lake further East.
