Louis II of Chalon-Arlay ( – 3 December 1463), nicknamed the Good, was Lord of Arlay and Arguel Prince of Orange. He was the son of John III of Chalon-Arlay and his wife, Mary of Baux-Orange, and the father of William VII of Chalon-Arlay. Louis was very ambitious. He tried to establish his authority in the Dauphiné, but failed. He did manage to extend his territory eastwards, to Neuchâtel and Lausanne. During his attempts to extend his territory, he would sometimes express loyalty towards the King of France, and at other times toward the German Emperor or the Duke of Burgundy. In the end, nobody really trusted him. 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. However, he was never able to realize this claim. The county of Geneva was held by Antipope Felix V. After Felix's death, Louis fought a long battle against the Counts of Savoy for control of Geneva. The struggle ended when the Emperor decided in favour of the House of Savoy.
