François Laurent d'Arlandes (French pronunciation: [fʁɑ̃swa loʁɑ̃ lə vjø daʁlɑ̃d]; 1742 – 1 May 1809) was a French marquis, soldier and a pioneer of hot air ballooning. He and Jean-François Pilâtre de Rozier made the first crewed free balloon flight, and first confirmed human flight of any kind, on 21 November 1783, in a Montgolfier balloon.
D'Arlandes was born in Anneyron in the Dauphiné. He met Joseph Montgolfier at the Jesuit college of Tournon. He became an infantry officer in the French royal guard.
