Bertrandon de la Bro(c)quière (c. 1400 – 9 May 1459) was a Burgundian spy and pilgrim to the Middle East in 1432–33. The book of his travels, Le Voyage d'Outre-Mer, is a detailed and lively account of the political situations and practical customs of the various regions he visited. He wrote it in French at the request of Philip the Good, Duke of Burgundy, for the purpose of facilitating a new crusade.
