Joan, Countess of Rethel

Joan of Rethel (died 1328), also known as Jeanne, was Countess of Rethel between 1285 and 1328.

She was the daughter of Hugh IV, Count of Rethel and his third wife Isabelle of Grandpré. She succeeded her father as Countess of Rethel in 1285.

In 1290, she married Louis I, Count of Nevers (who, in 1314 failed in his bid to become Holy Roman Emperor), son of Robert III, Count of Flanders. The marriage was "notoriously fractious".

They had two children:
 * Joan (1295–1375), married John of Montfort
 * Louis (1304–1346), Count of Flanders, Nevers and Rethel
