The Cathedral Group is a term applied to a collection of most of the tallest mountains of the Teton Range, all of which are located in Grand Teton National Park, in the U.S. state of Wyoming. The collection of mountains known as the Cathedral Group are classic alpine peaks, with pyramidal shapes caused by glacial motion. The highest peak in the group is Grand Teton, which rises more than 7,000 feet (2,100 m) above Jackson Hole valley, and is the second tallest mountain in Wyoming, after Gannett Peak.
