Mount Hooker () is located in the Wind River Range in the U.S. state of Wyoming. Mount Hooker was named for Joseph Dalton Hooker, the prominent 19th-century British botanist and explorer. The north and east slopes of Mount Hooker present some of the tallest and steepest vertical cliffs in Wyoming, and the peak is also remote, being more than from a road. The formidable north face of Mount Hooker was first climbed in 1964 by Yosemite Valley climber Royal Robbins, along with Dick McCracken and Charlie Raymond, who took over three days to scale the cliff face. In 2013, a team free climbed one pitch rated at , grade VI during a multiple-day ascent requiring five other pitches rated above 5.12.
Encountering bears is a concern in the Wind River Range. There are other concerns as well, including bugs, wildfires, adverse snow conditions and nighttime cold temperatures.
Importantly, there have been notable incidents, including accidental deaths, due to falls from steep cliffs (a could be fatal in this class 4/5 terrain) and due to falling rocks, over the years, including 1993, 2007 (involving an experienced NOLS leader), 2015 and 2018. Other incidents include a seriously injured backpacker being airlifted near SquareTop Mountain in 2005, and a fatal hiker incident (from an apparent accidental fall) in 2006 that involved state search and rescue. The U.S. Forest Service does not offer updated aggregated records on the official number of fatalities in the Wind River Range.
