Barronette Peak, Mountain summit in the Absaroka Range, Yellowstone National Park, Wyoming, United States

Barronette Peak is a summit in the Absaroka Range, in the northeast section of Yellowstone National Park, Wyoming, rising above the Lamar Valley a few kilometres south of the Montana border. Sources give its elevation as 10,354 feet (3,156 m) or 3,183 m. It is named after the guide Jack Baronett.

The Hayden Geological Survey named the peak in 1878 after Collins Jack Baronette, though his name was misspelled in the official record. This original misspelling has remained the official designation to the present day.

The name honours Collins Jack "Yellowstone Jack" Baronett, a Helena resident who in 1870 joined the search for Truman C. Everts, lost during the Washburn–Langford–Doane Expedition. In 1871 he built and ran the first bridge over the Yellowstone River near its confluence with the Lamar River, serving miners bound for Cooke City, Montana. The Hayden Geological Survey of 1878 named the peak for him but spelled it Barronette, and that spelling remains official.

The Barronette Trail starts at Soda Butte bridges on the Northeast Entrance Road and runs through conifer forests for several miles. Winter and early spring conditions can make the trail challenging, so warmer months offer easier hiking access.

The peak carries a misspelled name: the Hayden Geological Survey of 1878 recorded it as Barronette for Collins Jack "Yellowstone Jack" Baronett (1829–1901), and the extra letter was never corrected. Baronett built the first bridge over the Yellowstone River near its confluence with the Lamar in 1871 and joined the 1870 search for Truman C. Everts.
