The 1937–38 Coppa Italia was the fifth edition of the national cup in Italian football and the third edition of the tournament under the organization of the Direttorio Divisioni Superiori. The competition was won by Juventus.
The two finalists Torino and Juventus were both from Turin. A two-legged final was agreed upon given both teams had their own stadium to avoid either team having an advantage.
