The Blériot 165 (or Bl-165) was a French airliner of the 1920s. It was a four-engined biplane a final development in the family of designs that began with the Blériot 115. Two were built for Air Union to replace the Farman Goliath on their Paris-London route and were christened Léonard de Vinci and Octave Chanute. The airline found that it preferred the Liore-et-Olivier LeO 21s that it had ordered alongside this aircraft meaning that no further examples were produced.
