The Mauna Kea Observatories are observatories on Mauna Kea land managed by the Institute for Astronomy. Its altitude is 4205 meters (13796 feet). Some current observatories:

• Canada-France-Hawaii Telescope (CFHT) - 3.58-meter visible/infrared.
• Gemini North (Gemini Observatory) - 8.1-meter visible/infrared.
• IRTF - 3.0-meter infrared.
• James Clerk Maxwell Telescope (JCMT) - 15-meter submillimeter.
• Subaru Telescope - 8.2-meter visible/infrared.
• Submillimeter Array (SMA) - array of 6-meter radio telescopes.
• United Kingdom Infrared Telescope (UKIRT) - 3.8-meter infrared.
• UH88 - 2.2-meter visible/infrared.
• UH Hilo Hoku Ke'a - 0.9-meter visible.
• VLBA MK (VLBA) - 25-meter radio.
• Keck Observatory - 2 10-meter visible/infrared.

Former:

• Caltech Submillimeter Observatory (CSO) - 10.4-meter submillimeter (inactive).

Planned:

• Thirty Meter Telescope (TMT).

CSO has been decommissioned with removal plans in progress, and Hoku Ke'a and UKIRT are slated for future removal.

The Hawaiian Islands, which features tall mountain peaks with dry air and dark sky, also host observatories on Mauna Loa (Mauna Loa Solar Observatory), also on the island of Hawaii, and on Haleakala (Haleakala Observatory), on the island of Maui.
