The Savoia-Marchetti S.57 was an Italian single-engine biplane flying boat intended for aerial reconnaissance, built by Savoia-Marchetti for "Regia Aeronautica" after World War One.

Of wooden construction with a single-step hull, with pilot and observer/gunner in tandem open cockpits in the bow, the S.57 was powered by a single 186 kW (250 hp) Isotta-Fraschini V6. The observer had a single ring-mounted 7.7 mm (.30") FIAT machinegun.

Eighteen S.57s were accepted by "Regia Aeronautica" in 1925 and used as trainers.

A sole S.57bis (improved) was built, with a 224 kW (300 hp) Hispano-Suiza 42 engine.
