Round Barns in Illinois was the subject of a Multiple Property Submission to the National Register of Historic Places in the U.S. state of Illinois. The submission consists of 18 Illinois round barns located throughout the state. The list had major additions in 1982 and 1984. In 1983, 1992 and 2003 one property was added to the submission and in 1994 a historic district at the University of Illinois, including three round barns, was added to the submission and the National Register of Historic Places.
