The CAP-4 Paulistinha was a military and civilian trainer aircraft built in Brazil during the 1930s and 1940s. It was originally developed by Empresa Aeronáutica Ypiranga (EAY) as an unlicensed copy of the Taylor Cub powered by a Salmson 9Ad radial engine. It featured a high strut-braced wing, two enclosed tandem seats, and a steel-tube fuselage with fabric covering. Its tailwheel undercarriage was not retractable.

EAY had built five examples by the time that the firm was purchased by Companhia Aeronáutica Paulista (CAP) in 1942. CAP continued manufacturing the type under the designation CAP-4.
The type was widely successful, with nearly 800 units being produced for Brazil's flying clubs and armed forces, as well as for export to Argentina, Paraguay, Chile, Uruguay and Portugal. At the time of peak production in 1943, a new CAP-4 left the factory every day, and production continued until 1948.
In 1956, Sociedade Aeronáutica Neiva (Neiva) acquired the rights renaming it to P-56 Paulistinha, the design was used as the basis for an agricultural aircraft, the P-56 Agricola, adding a fibreglass chemical hopper and spraybars, but this was unable to compete with imported, purpose-built agricultural aircraft.
