Grand Staircase–Escalante National Monument, National Monument in southern Utah, United States.

Grand Staircase–Escalante National Monument is a 7,689 km² protected area in southern Utah, the largest of its kind in the contiguous United States. It has three geological parts: the Grand Staircase, a staircase of rock layers rising northward and cut by the Paria River; the Kaiparowits Plateau, its driest region; and the Escalante Canyons east of Fifty-Mile Mountain, whose eastern face is a 670 m escarpment.

President Bill Clinton established the monument in September 1996 under the Antiquities Act, with 1.7 million acres managed by the Bureau of Land Management. Donald Trump's December 2017 proclamation nearly halved it into three units, a reduction reversed by Joe Biden on 8 October 2021. Trump cut it again on 13 July 2026, to 181,500 acres.

More than a dozen archaeological sites bear witness to Pueblo and Fremont groups who lived for centuries under rock overhangs and in canyon alcoves throughout these lands. Many hikers come across rock art panels and pause in the stillness of these remote areas.

Visitors need permits for overnight camping, which can be obtained at several visitor centers or at developed trailheads. The area has both primitive sites and modern campgrounds with more facilities.

The monument was the last part of the contiguous United States to be mapped. A volunteer found a 75-million-year-old dinosaur near the Arizona border in 2002; in 2007 it was named Gryposaurus monumentensis, a duck-billed dinosaur at least 30 feet long with more than 800 teeth. Its fossils are held at the Natural History Museum of Utah in Salt Lake City.
