The Pink Cliffs are a series of highly dissected cliffs on the Colorado Plateau in Garfield, Iron, and Kane counties in southwestern Utah, United States. Contrary to the implication of the name, the cliffs are not a single set of rock formations, but actually a geological formation that manifests itself in multiple sets of rock formations.

The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries.
