Bogachiel Peak is a 5,478-foot (1,670 m) peak in the Olympic Mountains of Washington, U.S.. It is located in Olympic National Park. It is a high point on High Divide, and forms the southern end of Seven Lakes Basin. The peak is situated at the headwaters of the Bogachiel River. The name "Bogachiel" is a corruption of the Quileute words bo qwa tcheel el, or /boqʷač'íʔl/, from /bó:q'ʷa/, "muddy", and /číʔlowa/, "water", meaning "gets riley [turbid] after a rain", "muddy waters", or, less likely, "big river".
