American Fork Canyon, Natural canyon in Utah County, United States.

American Fork Canyon is a V-shaped gorge in the Wasatch Mountains, about 30 miles south of Salt Lake City, cut by the American Fork River. Its south side holds Timpanogos Cave National Monument. State Route 92, the Alpine Loop Scenic Byway, runs through it, with spurs to Tibble Fork Reservoir and Cascade Springs.

Native American tribes used the canyon for centuries before settlers established mining and transportation routes in the late 1800s. This early development shaped how humans have used the land ever since.

The canyon's name comes from the American Fork River, which runs along its floor. Fremont people left pictographs several thousand years old on rock faces and walls lining the canyon, and spearpoints, grindstones and arrowheads found in small caves suggest hunters used them as temporary camps. Campgrounds such as Timpooneke and Granite Flat are the summer base for visitors.

The main access road operates from May through October with seasonal closures expected. Visitors should prepare for varying weather conditions and bring appropriate gear for their chosen activity level.

The canyon was also a pilot site for the Recreation Fee Demonstration Project, which became the Federal Lands Recreation Enhancement Act in 2005.
