John I (15 November 1316 – 20 November 1316), called the Posthumous, was King of France and Navarre, and Count of Champagne, as the son and successor of Louis X, for the five days he lived. He thus had the shortest official reign of any French king.

He was born a king of the House of Capet and the posthumous son of Louis X and Clémence d'Anjou.

John lived for only a few days and many believed his uncle, the future King Philip V, caused his death in order to gain the throne. There were also stories that Philip had the child kidnapped and substituted a dead child in his place. During the 1350s, a man named Giannino di Guccio Baglioni [1], claiming to be King John I, appeared in Provence. He was quickly put in prison in December 1360 and died there.

John reigned for five days under his uncle's regency, until his death on 20 November 1316. The infant King was buried in Saint Denis Basilica. He was succeeded by his uncle, Philip V.
