Hemingway–Boulders Wilderness, Protected wilderness area in central Idaho, United States.

Hemingway–Boulders Wilderness is a 67,998-acre protected area in the Boulder Mountains of central Idaho, within Sawtooth National Forest and the Sawtooth National Recreation Area. It spans Blaine and Custer counties, adjoins the Jim McClure–Jerry Peak Wilderness to the northeast, and lies south of the Cecil D. Andrus–White Clouds Wilderness.

The Hemingway–Boulders Wilderness entered the National Wilderness Preservation System on August 7, 2015, through the Sawtooth National Recreation Area and Jerry Peak Wilderness Additions Act (Public Law 114–46). Sponsored by Representative Mike Simpson, the bill passed Congress without objection and was signed by President Barack Obama.

The name pairs the Boulder Mountains with Ernest Hemingway, who lived in nearby Ketchum. The wilderness sits in the Sawtooth National Recreation Area, so the writer's adopted Idaho home and the range behind it share one federal designation.

Visitors must follow strict rules that ban motorized equipment including vehicles and bicycles. Practicing Leave No Trace principles helps keep this wild area in its natural state throughout your visit.
