The National Solar Observatory (NSO) is a United States federally funded research and development center for solar physics headquartered in Boulder, Colorado. It was founded in 1984 and is operated by the Association of Universities for Research in Astronomy.

NSO manages several ground-based solar telescopes and observatories including the 4-meter Daniel K. Inouye Solar Telescope at the Haleakala Observatory; the Sunspot Solar Observatory near Sunspot, New Mexico; and six sites around the world for the Global Oscillations Network Group, one of which is shared with the Synoptic Optical Long-term Investigations of the Sun. NSO also operates the NSO Integrated Synoptic Program (NISP), which combines and coordinates synoptic solar observations for research and space weather applications.
