Kepler Cascades is a waterfall on the Firehole River in southwestern Yellowstone National Park in the United States. The cascades are located approximately 2.5 miles south of Old Faithful. The cascades drop approximately 150 feet over multiple drops. The longest drop is 50 feet. The cascades are located very near to and visible from the Old Faithful to West Thumb road.
The cascades were named by Philetus Norris, park superintendent in 1881 for the 12 year old son of Wyoming's territorial governor John Wesley Hoyt. Hoyt and his son, Kepler Hoyt, were visiting Yellowstone in 1881 when Norris named the cascades after Kepler.
