The IAe.31 Colibrí ("Hummingbird") was a civil trainer aircraft developed in Argentina in the 1940s. It was designed by Émile Dewoitine and developed by the Instituto Aerotécnico for manufacture by the company H. Goberna factories in Córdoba Province as an initiative under President Juan Perón's first five year plan.

The design used the AeC.3G of the early 1930s as a starting point, but was a considerably modernised aircraft. Like the AeC.3G, however, it was a conventional low-wing cantilever monoplane with seating for student pilot and instructor in tandem and fixed tailwheel undercarriage. Unlike its predecessor, the cockpits were enclosed under a long canopy. Only three examples were built.
