Jean Poton de Xaintrailles (; c. 1390 – 7 October 1461), a minor noble of Gascon origin, was one of the chief lieutenants of Joan of Arc.
He served as master of the royal stables, as royal bailiff in Berry and as seneschal of Limousin. In 1454 he was appointed a Marshal of France. Jean Poton was a leading figure on the French side in the Hundred Years War.

He fought at the battle of Verneuil in 1424. His participation, along with Joan of Arc, in the battle at Orléans in 1429 led to the end of the Siege of Orléans. Jean Poton fought numerous battles alongside Joan of Arc during the Loire Campaign and retained a lifelong support for her. With La Hire, he even tried, albeit in vain, to rescue Joan after she was captured. Believing Joan was being held captive in Compiègne, Jean Poton captured it, only to learn that the prisoner had already been moved to Rouen.
