It is the flagship university of the University of Colorado system and was founded five months before Colorado was admitted to the union in 1876. According to The Public Ivies: America's Flagship Public Universities (2001), it is considered one of the prestigious "Public Ivy League" schools.

Six Nobel Laureates, seven MacArthur Fellows, and 17 astronauts have been affiliated with CU-Boulder as students, researchers, or faculty members in its history. The university received nearly US$454 million in sponsored research in 2010 to fund programs like the Laboratory for Atmospheric and Space Physics, JILA, and National Institute of Standards and Technology's NIST-F1 atomic clock.
