West Peak is a peak in the Olympic Mountains, in Jefferson County of Washington state. Rising in the center of Olympic National Park, it is the highest peak on the Anderson Massif. West Peak is the hydrographic apex of the Olympic Mountains, with precipitation runoff flowing outward to the Pacific Ocean via Quinault River, the Strait of Juan de Fuca via Elwha River, and Hood Canal via the Dosewallips River. The Eel Glacier is situated in a cirque east of the summit, and an unnamed glacier resides in the south cirque. Its nearest higher peak is Mount Mystery, to the northeast. The first ascent of the peak was made in 1930 by E. B. Hamilton. Legend has it that the mountain's name is for Mr. West, a participant in the 1890 O'Neil Expedition, rather than for its apparent position on the Anderson Massif. The West Branch of the Quinault River was named after him in 1890.
