The University of Illinois Astronomical Observatory, located on the campus of the University of Illinois at Urbana-Champaign, was built in 1896 and was designed by Charles A. Gunn. It has been listed on the National Register of Historic Places since November 6, 1986, and on December 20, 1989, was designated a National Historic Landmark.

The observatory played a key role in the development of astronomy as it was home to a key innovation in the area of astronomical photometry. The facility has been directed by such noted scientists as Joel Stebbins and Robert Horace Baker. Erected at the behest of the Illinois General Assembly, the University of Illinois Observatory became important in the development of astronomy due, in large part, to pioneering research by Dr. Stebbins, from 1907 to 1922. Joel Stebbins left the University of Illinois in 1922 but left behind a legacy of discovery that helped alter the face of modern astronomy. The building served the University of Illinois astronomy department from its opening until 1979, when the department moved into a new, larger building to house its growing staff. Though none of the astronomical instruments are being used for professional research today, the observatory still contains a 12" Brashear refractor that is used as a teaching tool in the university's astronomy classes.
