The ARO 12m Radio Telescope (ARO12m or KP12m) is a 12-meter dish located on Kitt Peak, approximately 60 mi (97 km) from Tucson in Arizona at an elevation of 6,215.8 ft (1,894.6 m).

The original dish was built in 1967 under the umbrella of the National Radio Astronomy Observatory (NRAO).

In 2000, the NRAO passed control of the telescope to the University of Arizona.

The University of Arizona had been operating the Submillimeter Telescope (SMT) located on Mount Graham since 1992.

[1] In the almost 40 years since it was first built, the 12m Radio Telescope has been at the forefront of millimeter molecular astronomy: studying molecules in space through the use of molecular spectroscopy at millimeter wavelengths.
