大峡谷国家公园（Grand Canyon National Park）是美国西南部的国家公园，在1979年被列为世界自然遗产，以深达1500米，由科罗拉多河耗费万年所切割出来的科罗拉多大峡谷景观闻名于世。位于美国亚利桑那州的西北角。整个大峡谷走向为东西向，总长有349公里，宽度从最窄的6公里到25公里。将大峡谷分为南缘跟北缘。整个国家公园总面积为1,217,403亩。在地形上是高原地形，该地的高原称为凯巴布高原（Kaibab）。
大峡谷国家公园是1908年美国总统罗斯福所提倡与规划的，初时只叫做国家纪念公园，在1911年划立了国家保护区。
1919年的2月26日，经过美国国会的法案通过，正式将大峡谷最深、景色最壮丽的一段，约有170公里长度的区域，成立了大峡谷国家公园，并建立起步道系统、生态与地质学的教育研究系统。
目前大峡谷国家公园是全美最受欢迎的国家公园之一，据统计，每年的参观人次约有400万。
The Grand Canyon is a steep-sided canyon carved by the Colorado River in the state of Arizona in the United States. It is contained within and managed by Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Tribal Nation, the Havasupai people and the Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.
The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters). Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.
