Buckskin Gulch (also known as Buckskin Creek, Buckskin Wash, and Kaibab Gulch) is a gulch and slot canyon in southern Kane County, Utah, United States, near the Arizona border. It is one of the main tributaries of the Paria River, which is itself a minor tributary of the Colorado River. At over 13 miles (21 km) long, Buckskin Gulch is the longest and deepest slot canyon in the Southwestern United States (and possibly the longest in the world), making it a major attraction for hikers and canyoneers that receives a high amount of foot traffic.

The canyon is often visited in conjunction with the longer Paria Canyon, although some prefer to make a long day trip out of the hike. With a distance of 20 miles (32 km), hiking both canyons in one day is possible. Wire Pass, a short tributary to Buckskin, is a popular day-hike alternative that still takes hikers through the narrow, curving features that are the hallmarks of slot canyons.
