The IMAM Ro.57 was an Italian twin-engined, single-seat monoplane fighter of the Regia Aeronautica. Based on a 1939 design by Giovanni Galasso the aircraft did not enter production until 1943. By the time it entered service it was considered obsolete.
Two hundred aircraft were ordered, but only 50-75 were produced in two versions, one flown as an interceptor, the other in the role of a ground attack aircraft.
