Saddle Mountain is a mountain summit located in Yellowstone National Park, in Park County, Wyoming, United States.
The peak is situated in the northeast quadrant of Yellowstone National Park and is the 20th-highest peak within the park. It is part of the Absaroka Range, which is a subset of the Rocky Mountains. Neighbors include Little Saddle Mountain 1.5 mile to the southwest, Castor Peak 3.98 miles to the south-southeast, and Pollux Peak 4.07 miles to the southeast on the opposite side of the Lamar River Valley. Topographic relief is significant as the southeast aspect rises above Lamar River in approximately two miles. The mountain's name, which was officially adopted in 1930 by the United States Board on Geographic Names, was in use before 1899 when Henry Gannett published it in A Dictionary of Altitudes in the United States.
