The Sud-Ouest Corse was a French mail and passenger transport aircraft, built by SNCASO.

[1] The Corse began as the S.O.90 Cassiopée, a nine-passenger aircraft.

The aircraft was a cantilever mid-wing monoplane, powered by two Renault 12S engines with a retractable conventional landing gear.

Intended to serve Air France, it failed their aircraft requirements.

60 aircraft were built for Aeronavale, and a small number for other overseas airlines.
