The Submillimeter Telescope (SMT), formerly known as the Heinrich Hertz Submillimeter Telescope, is a submillimeter wavelength radio telescope located on Mount Graham, Arizona. It is a 10m dish inside a building to protect it from bad weather that can be completely rolled away when the telescope is in use. The telescope's construction was finished in 1993. With the 12 Meter Telescope on Kitt Peak, it is maintained by the Arizona Radio Observatory.

The telescope is used 9-10 months of the year and is only stowed when there is too much water vapor in the atmosphere, primarily during the summer. It is one of the telescopes that makes up Mount Graham International Observatory.
