The SIPA S.90 was a French-built two-seat light touring and training aircraft of the 1940s and 1950s.

The SIPA S.90 was designed by Yves Gardan for the Societe Industrielle pour l'Aeronautique (SIPA). The prototype first flew on 15 May 1947, winning a French government competition for a new light two-seat aircraft for operation by the French aero clubs.

The initial production S.90 was a low-wing aircraft with fixed tailwheel undercarriage and side-by-side seating for two. It was powered by a 75 hp (56 kW) Mathis G4F engine. Four examples were built.

100 aircraft were ordered by the French government, on behalf of the aero clubs, and these were powered by the 75 hp (56 kW) Minie 4DC engine as the SIPA S.901. The first made its initial flight on 25 June 1948. Deliveries were completed in the early 1950s. Various engines were later installed in the S.901, giving rise to new model numbers.

In later years, the S.90 series readily found buyers in the secondhand market and examples have flown with private owners in Belgium, Germany, Switzerland and the United Kingdom. Nine further aircraft were built later with plywood covering in lieu of fabric, receiving new designations. In 2001, 15 examples remained airworthy in France, Switzerland and the UK.

Total production of all models was 113 aircraft.
