University of Illinois Willard Airport is an airport owned and operated by the University of Illinois at Urbana-Champaign located in Tolono Township, just south of Savoy, Illinois, a small village that is part of the Champaign-Urbana Metropolitan Area. It serves the greater Champaign-Urbana area and most of East Central Illinois. The airport is also served by the Champaign-Urbana Mass Transit District.

Visitors from around the world frequently fly into Champaign-Urbana in order to collaborate with researchers at the university or to conduct business with companies in the university's research park. However, many airlines have chosen to serve Central Illinois through the Bloomington-Normal airport instead. Due to the lack of U.S. immigration and customs facilities, no international flights are offered, and the additional price airlines charge to fly to Willard Airport compared to a major hub like Chicago's O'Hare Airport ensures that budget-minded travellers use surface transport to reach Champaign County.

Willard Airport is home to the University of Illinois Institute of Aviation, which is a major research facility at the university. It has the distinction of being one of the few University-owned research airports. The Institute of Aviation is ranked amongst the top 10 programs in the nation, and the Institute's facilities have won numerous prestigious awards.
