Hock Mountain, mountain summit in the North Cascades, Washington, United States

Hock Mountain is a 7,750-foot summit in the Methow Mountains, a subset of the North Cascades, on the triple boundary of North Cascades National Park, Lake Chelan-Sawtooth Wilderness and Lake Chelan National Recreation Area. Its north face is steep granitic rock, while the more moderate west slope allows a scramble ascent. The pointed peak carries snow patches above dark conifer forest.

The mountain sits at the boundary between North Cascades National Park and two wilderness areas and was recognized by hikers as a distinct peak relatively late. Its name emerged informally from local references rather than from any formal naming tradition.

The mountain serves as a natural boundary between Chelan and Okanogan counties, representing the geographical divisions of Washington State's administrative territories.

The mountain is reached via the Pacific Crest Trail accessible east of Rainy Pass with several trail junctions along the route to the summit. The best hiking season runs from early summer through fall when snow and ice have melted away.

Hock Mountain sits on the triple boundary of North Cascades National Park, Lake Chelan-Sawtooth Wilderness and Lake Chelan National Recreation Area, and on the Chelan–Okanogan county line. Its north face is steep granitic rock, while the west slope is moderate enough for a scramble. Stiletto Peak, the nearest higher neighbour, lies 2.24 miles due north.
