Kathryn Chicone Ustler Hall is a historic building on the campus of the University of Florida (UF) in Gainesville, Florida. It was designed by William Augustus Edwards in the Collegiate Gothic style and opened in 1919 as the University Gymnasium. In that capacity, the building was the first home of the Florida Gators men's basketball team, and it continued to serve as the home court for most of the university's indoor sports programs until the Florida Gymnasium opened in the late 1940s. The university became co-educational at about the same time, and the building was rechristened the Women's Gymnasium and was repurposed as a recreation center for the school's many new female students. On June 27, 1979, it was added to the U.S. National Register of Historic Places.
