Lituya Mountain is a peak in the Fairweather Range of Alaska, United States, south of Mount Fairweather. Its eastern slopes feed a branch of the Johns Hopkins Glacier, which flows into Glacier Bay. On its western side is a large cirque, shared with Mount Fairweather, Mount Quincy Adams, and Mount Salisbury, which heads the Fairweather Glacier; this flows almost to the Pacific coast at Cape Fairweather.
