Roger Béteille (28 August 1921 – 14 June 2019) was a French aeronautical engineer and businessman who was associated with Airbus.

[2] He also decided that English should be the working language and that measurements should not be metric because most airlines already had American-built aircraft.

[11][12] He long served as the company's chief operating officer and was regarded as one of the founding fathers, along with Henri Ziegler and Felix Kracht.

[15] Béteille was awarded the Ludwig Prandtl Ring from the Deutsche Gesellschaft für Luft- und Raumfahrt (German Society for Aeronautics and Astronautics) in 1986.

[17] Béteille was married to opera singer Josette Jasmin and the two lived in Cannes and on the Midi.
