The Fiat A.74 was a two-row, fourteen-cylinder, air-cooled radial engine produced in Italy in the 1930s as a powerplant for aircraft.

It was used in some of Italy's most important aircraft of World War II.

Fiat had made a number of smaller radial air engines over the years but the A.74 marked a major increase in power and size.

The A.74 family was widely produced and spawned a number of related engines such as the A.76, A.80, and A.82, each successive generation being larger and more powerful than the previous.
