Olallie Lake is a freshwater lake located on a prominent valley at the western base of Pratt Mountain, between Mount Defiance and Bandera Mountain, in King County, Washington. The name means berry in Chinook Jargon.
Olallie Lake is surrounded by other alpine lakes, including Talapus Lake to the south and Pratt Lake a short distance north. Because of its proximity to Snoqualmie Pass and other prominent peaks in the Alpine Lakes Wilderness, the lakes are a popular area for hiking, swimming, and fishing rainbow trout.
