Aéroplanes Voisin was a French aircraft manufacturing company established in 1905 by Gabriel Voisin and his brother Charles, and was continued by Gabriel after Charles died in an automobile accident in 1912; the full official company name then became Société Anonyme des Aéroplanes G. Voisin. During World War I, it was a major producer of military aircraft, notably the Voisin III. After the war Gabriel Voisin abandoned the aviation industry, and set up a company to design and produce luxury automobiles, called Avions Voisin.

The 1907 Voisin biplane, was Europe's first successful powered aircraft, designed by aeronautical engineer and manufacturer Gabriel Voisin. It was used by the French aviator Henri Farman to make the first heavier-than-air flight lasting more than a minute in Europe, and also to make the first full circle. The first examples of the aircraft were known by the name of their owners, for instance the Delagrange I, or the Henri Farman n°1. Farman made many modifications to his aircraft, and these were incorporated into later production aircraft built by Voisin. The type enjoyed widespread success, and around sixty were built.
