Hinkle Fieldhouse is a basketball arena on the campus of Butler University in Indianapolis, Indiana. Completed in early 1928, it was the largest basketball arena in the United States until 1950. The facility was renamed Hinkle Fieldhouse in 1966 in honor of Butler's longtime coach and athletic director, Paul D. "Tony" Hinkle. It is the sixth-oldest college basketball arena still in use. Added to the National Register of Historic Places in 1983 and designated a U.S. National Historic Landmark in 1987, Hinkle Fieldhouse is sometimes referred to as "Indiana's Basketball Cathedral."
