John of Artois, Count of Eu, French soldier (d. 1387)
John of Artois (29 August 1321 – 1387), called "sans Terre" (Lackland), was the son of Robert III of Artois and Joan of Valois. The confiscation of his father's goods for attempted fraud in 1331 had left him without an inheritance.

He was badly wounded at the Battle of Poitiers on 19 September 1356, and was captured there by the English. Enormously rich his ransom was sold to the Edward the Black Prince by his captor Élie de Pommiers for 30,000 old écus.
He married Isabeau of Melun (1328–1389), daughter of John I of Melun, Count of Tancarville, on 11 July 1352 and had the following issue:
Joan (1353–1420), married at the Château d'Eu on 12 July 1365 Simon de Thouars (d. 1365), Count of Dreux
