Ron Calcagni (born February 6, 1957) is a former quarterback for the University of Arkansas Razorbacks football team from 1975 to 1978. Calcagni was born in Youngstown, Ohio. An All-State in high school, Calcagni was initially recruited by Bo Rein to play for North Carolina State University. However, Rein left North Carolina State to coach under Frank Broyles at Arkansas and convinced Calcagni to follow him there. Rein would return to North Carolina State as head coach before Calcagni graduated from Arkansas.

Calcagni had a record setting career with Arkansas. His 25-4-2 winning record made him the winningest quarterback in Razorbacks history. Calcagni is perhaps best known for his role in the defeat of the heavily favored #2 ranked Oklahoma Sooners in the 1978 Orange Bowl. Following that upset victory Calcagni and head coach Lou Holtz were on the September 11th, 1978 cover of Sports Illustrated Magazine. He also helped the Razorbacks to a 1976 Cotton Bowl Classic victory over the University of Georgia and a Fiesta Bowl tie with UCLA.

During his time at Arkansas Calcagni played alongside Chicago Bears great Dan Hampton, running back Ben Cowins and record setting kicker Steve Little. The Razorbacks went 10-2 in 1975, 5-5-1 in 1976, 11-1 in 1977 and 9-2-1 in 1978 with Calcagni as starting quarterback.
