The Alfa Romeo 115 was an Italian 6-cylinder air-cooled inverted inline engine for aircraft use, mainly for training and light planes, based on the de Havilland Gipsy Six engine. Production totalled approximately 1,600 units. Derivatives of the 115 include the -1, bis, ter and Alfa Romeo 116.

The Alfa Romeo 115 series of engines closely follows the original de Havilland Gipsy Six engines in having 1-piece Elektron casting crankcases with cover plates, steel cylinders, finned for cooling, and detachable aluminium alloy cylinder heads. The 6-throw 1-piece counterbalanced crankshaft is carried in seven plain journal bearings and the propeller is driven directly by the crankshaft.
