The Teton Range is a mountain range of the Rocky Mountains in North America. A north-south range, it is on the Wyoming side of the state's border with Idaho, just south of Yellowstone National Park. The two principal summits are the Grand Teton at 13,770 ft (4198 m) and Mount Owen at 12,928 feet (3,940 m); most of the range is within the Grand Teton National Park. Early French voyageurs gave the name "les Trois Tétons" (the three breasts).
