Cathedral Group, Mountain peaks in Grand Teton National Park, Wyoming, US.

The Cathedral Group is the cluster of the tallest peaks in the Teton Range, in Grand Teton National Park, Wyoming. Grand Teton rises more than 7,000 feet (2,100 m) above Jackson Hole valley, the second tallest mountain in Wyoming after Gannett Peak. The group also holds Mount Owen, Middle Teton, South Teton, Teewinot Mountain, Teepe Pillar, Cloudveil Dome, Nez Perce Peak and Buck Mountain, eight of the range's ten highest summits. Cascade Canyon bounds it to the north and Avalanche Canyon to the south.

The Cathedral Group's name comes from the spire-like forms of Grand Teton, Mount Owen and Teewinot Mountain, the three peaks some geographers treat as the group proper. Other definitions extend it to all major summits between Cascade Canyon to the north and Avalanche Canyon to the south, including Middle Teton, South Teton, Teepe Pillar, Cloudveil Dome, Nez Perce Peak and Buck Mountain. Eight of the ten highest summits in the Teton Range lie within this cluster.

The name comes from the spire-like profiles of Grand Teton, Mount Owen and Teewinot Mountain, which some geographers treat as the group proper; others add Middle Teton, South Teton, Teepe Pillar, Cloudveil Dome, Nez Perce Peak and Buck Mountain because Cascade and Death Canyons cut them off from the rest of the range. Eight of the ten highest summits in the Teton Range stand here.

The group is bounded by Cascade Canyon to the north and Avalanche Canyon to the south, so approaches start from the Jenny Lake and Lupine Meadows trailheads. Jenny, Bradley and Taggart Lakes sit at the base of the peaks, and the Teton Glacier lies high on the Grand Teton's north face. Snow lingers on the upper cirques and arêtes into summer.

Some geographers count only Grand Teton, Mount Owen and Teewinot Mountain as the Cathedral Group proper; others include every major peak between Cascade and Avalanche Canyons, since the deep canyons isolate them together. The group holds eight of the ten highest summits in the Teton Range.
