Thor Peak, Mountain summit in Grand Teton National Park, Wyoming, United States

Thor Peak is a mountain summit in the northern Teton Range that reaches approximately 12,000 feet in elevation. Glaciers cover its eastern and northern slopes, creating steep snow and ice faces that characterize the peak's appearance.

Thor Peak lies in the northern Teton Range, about 1 mile (1.6 km) east of Mount Moran, between Moran Canyon to the north and Leigh Canyon to the south. It is the eighth-highest summit of the range at 12,033 feet (3,668 m). Its east and north slopes hold several semi-permanent snowfields and the Triple Glaciers.

Thor Peak is named after Thor, the Norse god of thunder, a name shared with other Teton features such as Mount Moran's nearby landscape. The peak's two enclosing canyons, Moran Canyon to the north and Leigh Canyon to the south, are named for early explorers and settlers of the range. Climbers today approach it as one of the range's less-visited summits.

Thor Peak sits between Moran Canyon to the north and Leigh Canyon to the south, about 1 mile (1.6 km) west of Mount Moran. The easiest line, the south slope, is rated class 4, but the remote position and hard approach mean few parties attempt it. Plan for high-altitude weather and self-sufficient route-finding on the snowfields and Triple Glaciers of the north and east slopes.

Thor Peak is the eighth-highest summit in the Teton Range, and its two deep bordering canyons, Moran Canyon to the north and Leigh Canyon to the south, cut it off from easy approaches. The Triple Glaciers lie on its north flank, while semi-permanent snowfields remain on the east and north slopes.
