The Teton Range is a mountain range of the Rocky Mountains in North America. A north-south range, it is mostly on the Wyoming side of that state’s border with Idaho, just south of Yellowstone National Park. Most of the east slope of the range is in Grand Teton National Park. Early French Voyageurs used the name les trois tétons (the three breasts). It is likely that the Shoshone people once called the whole range Teewinot, meaning “many pinnacles”. The principal summits of the central massif, sometimes referred to as the Cathedral Group, are Grand Teton (), Mount Owen (), Teewinot (), Middle Teton () and South Teton (). Other peaks in the range include Mount Moran (), Mount Wister (), Buck Mountain () and Static Peak ().
