|Organisation||NSO, HAO, NJIT, UH IfA and UChicago|
|Location(s)||Haleakala Observatory, Hawaii, United States|
|Wavelength||300nm – 12µm|
|Telescope style||Off-axis, all-reflecting Gregorian telescope|

The Daniel K. Inouye Solar Telescope (DKIST), formerly Advanced Technology Solar Telescope (ATST), is a large domed solar telescope facility with 4 meter wide primary mirror that is under construction by the National Solar Observatory atop the Haleakala volcano on the Pacific island of Maui. The telescope was officially named after late Hawaii Senator Daniel K. Inouye in December 2013, while still under construction. On completion around 2018, it will be the world's largest solar telescope.
DKIST features an off-axis, clear aperture design to allow for observations with unprecedented spatial, spectral and temporal resolution. Avoiding a central obstruction is important to minimize scattered light when observing the faint solar corona, but it also eases operation of adaptive optics and later image reconstruction such as speckle imaging.
The site on Haleakala was selected for its clear daytime atmospheric seeing conditions, which will enable study of the solar corona. The DKIST enclosure will house the solar telescope, capable of observing features on the Sun that are only 30 km across.
