The FMA 20 El Boyero (Shepherd) was a light utility aircraft produced in Argentina in the 1940s. It was a conventional high-wing strut-braced monoplane with fixed tailskid undercarriage with seating for two side-by-side in an enclosed cabin. Design work started in 1939 and two prototypes were built the first flying in November 1940 and the second early the following year.
