Charles de Croÿ Prince of Chimay (Dutch: Karel van Croij; 1506 – 11 December 1564) was a bishop of the See of Tournai in present-day Belgium from 1524 until 1564.

He was a nephew of William de Croÿ, Lord of Chièvres (1458–1521) and a brother of William de Croÿ, Archbishop of Toledo (1498–1521).

Among Charles' teachers were Adrianus Barlandus, Jacobus Latomus, and Johannes Driedo.

A biography of Pierre Cotrel, vicar-general of the Diocese of Tournai from 1497 to 1545, mentions Charles,[1] as do materials describing a château he built in the village of Moorsel in 1546.
