Charles I de Croÿ (1455–1527), Count and later 1st Prince of Chimay, was a nobleman and politician from the Low Countries in the service of the House of Habsburg.

Charles was born into the House of Croÿ as the eldest son of Philip I of Croÿ-Chimay and Walburga of Moers.

He was saved by Maximilian, Josse de Lalaing and a few Germans who came to his rescue, risking being enveloped themselves.

[1] Charles was in 1519 one of the negotiators during the talks which led to a military alliance with John II, Duke of Cleves.

He was also stadtholder of the County of Hainaut and governor of Valenciennes, but he resigned in 1521 in favour of his son-in-law, Philippe II de Croÿ.
