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.In 1352, he was created Count of Eu, a title earlier forfeited at the execution of the previous holder, Raoul II of Brienne.
He was badly wounded at the Battle of Poitiers on 19 September 1356, and was captured there by the English.
