is the United States' national facility for ground-based, night-time optical and infrared astronomy.

NOIRLab runs four observatories and a center for scientific software and research data archiving.

NOIRLab was formed in 2019 by the merger of three predecessor organizations, which were all managed by AURA and funded by NSF.
