Dunraven Peak, Mountain summit in Yellowstone National Park, Wyoming, US.

Dunraven Peak is a mountain summit in the Washburn Range within Yellowstone National Park, standing at 9,869 feet elevation. The summit provides panoramic views of the Grand Canyon of the Yellowstone and the surrounding mountain ranges in the park.

The peak was named in 1878 by Henry Gannett to honor the Earl of Dunraven, a traveler who documented his Yellowstone journey in 1874. This naming reflects the early exploration and foreign visitors who helped shape the park's history.

The name comes from the 4th Earl of Dunraven and Mount-Earl, an Anglo-Irish peer who joined a Texas Jack Omohundro hunting expedition to the Northern Rockies in 1874 and gave over 150 pages of his book The Great Divide, published in London that year, to Yellowstone. Henry Gannett of the U.S. Geological Survey named the peak for him in 1878.

Dunraven Peak is rarely climbed and has no maintained trail to its summit; the German source notes it is seldom ascended, unlike nearby Mount Washburn. Approach from Dunraven Pass on the Grand Loop Road between Tower and Canyon, the pass named for the peak in 1879. Route-finding and steep, loose ground are likely, so carry a map and be ready to turn back.

Dunraven Peak is rarely climbed, unlike nearby Mount Washburn. Henry Gannett named it in 1878 for the 4th Earl of Dunraven, whose 1874 book The Great Divide devoted over 150 pages to Yellowstone. In 1879 Superintendent Philetus Norris gave Dunraven Pass on the Grand Loop Road its name because of its proximity to the peak.
