Louis II of Chalon-Arlay (c. 1388 – 3 December 1463), nicknamed the Good, was Lord of Arlay and Arguel Prince of Orange.

In 1421, he was appointed the Imperial vicar of Burgundy by the Holy Roman Emperor Sigismund.

During his attempts to extend his territory, he would sometimes express loyalty towards the King of France, and at other times toward the Emperor Sigismund, or the Duke of Burgundy.

Louis was also active in the Netherlands: in 1425, he led an army sent by Philip the Good to support Duke John IV of Brabant in a war against his wife Jacqueline.

Louis also called himself Count of Geneva, claiming it was part of the inheritance he had received from his mother.
