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

Hedges Peak is a mountain summit in the Washburn Range within Yellowstone National Park that rises to approximately 9,669 feet. The peak features steep eastern slopes with exposed rocky formations and sparse vegetation typical of the high alpine zone.

The peak was named in 1895 by geologist Arnold Hague after Cornelius Hedges, a member of the Washburn-Langford-Doane Expedition of 1871. That expedition conducted some of the first scientific surveys of the Yellowstone region and its findings helped establish the park.

The name honours Cornelius Hedges (1837–1907), a Montana lawyer on the 1871 Washburn–Langford–Doane Expedition. His accounts of the expedition, printed in the Helena Daily Herald, fed the campaign that led to the creation of Yellowstone National Park.

The hike is best attempted during summer months when trails are clearly visible and snow has melted. Winter access requires specialized gear and mountain experience, making visits outside the summer season more demanding.

Before 1895 the peak bore the name Surprise Peak, given by geologist J.P. Iddings in 1883; the sources record the name but not why he chose it. In 1895 Arnold Hague renamed it for Cornelius Hedges, whose expedition reports in the Helena Daily Herald backed the park's creation.
