The SECAT S-5 was a light, high-wing, two-seat touring monoplane aircraft, designed and built by the Société d'Etudes et de Construction d'Avions de Tourisme in France shortly after the end of World War II.

Only one example of the type was ever built, and it flew for a variety of private owners for several decades.

The S-5 was based on the design of the S-4,[2] and was of all-wooden construction and had side-by-side seating for two persons.

The cantilever, elliptical high-set wing comprised a wooden box-spar, chordwise ribs and a stressed plywood skin.

The sole example of the SECAT S-5, registered F-PIIC, was initially operated from Toussus-le-Noble Airport, near Paris.
