The SNCASO SO.8000 Narval was a French carrier-based strike fighter designed by Sud-Ouest in the late 1940s. The French Navy ordered two prototypes in 1946 and they made their maiden flights three years later. They were plagued by aerodynamic problems and unreliability issues with their piston engines. The aircraft proved to be slow, lacking in lateral and longitudinal stability and unsuitable for carrier operations; it did not enter production.

SNCASO was a French aircraft manufacturer.
