The County of Amiens (also: Amiénois) was a feudal state centred on the city of Amiens, northern France, that existed from the 9th century until 1077 when the last count became a monk and the county reverted to the French crown.

In 1185 the county was united with the French crown under King Philip II of France.

Valois went to his brother-in-law Herbert IV, Count of Vermandois, Amiens reverted to the French king Philip I while Vexin was divided between William, Duke of Normandy, and the king of France.

Bar-sur-Aube and Vitry were occupied by Theobald, Count of Blois.
