Corbeyran de Cardaillac de Sarlabous was a 16th-century French soldier who served in Scotland as Captain of Dunbar Castle, and was Governor of Le Havre for twenty years. He was usually called Captain Sarlabous in Scottish and English letters of his time. A contemporary French writer calls him the "sieur de Sarlaboz." Sarlabous is a place in the Hautes-Pyrénées where Corbeyran held lands.
Born around 1515 in Gascony, his father was Odet de Cardaillac, seigneur de Sarlabous, and his mother, Jeanne de Binos, heiress of Bize or Vize.
