SNCASO (abbreviated from Société nationale des constructions aéronautiques du Sud-Ouest, or commonly, Sud-Ouest) was a French aircraft manufacturer.

Created during 1936 as one of seven nationalised aeronautical manufacturing companies, SNCASO became a key French aircraft manufacturer following the end of the Second World War. It produced numerous innovation aircraft; amongst the company's more notable projects was the first French jet aircraft, the Sud-Ouest Triton, and the first indigenously-developed French helicopter, the Sud-Ouest Djinn.

On 1 March 1957, SNCASO merged with another French nationalised aviation company, SNCASE, (Société nationale des constructions aéronautiques du Sud-Est), to form Sud Aviation.
