Mount Graham is a mountain in southeastern Arizona in the United States. The mountain reaches 10,720 feet (3267 meters) in height, and is home to some of the clearest skies in the world. It is home to the Mount Graham International Observatory area, where multiple organizations have set up large telescopes in a few separate observatories.

The United States Congress authorized construction of observatories on the mountain in 1988, but there has been outcry from some Native American groups, who consider the site to be sacred.
