John II, Count of Nevers (known as Jean de Clamecy, prior to acquiring title of "Count of Nevers"; 1415–1491) was a French noble.He was the son of Philip II, Count of Nevers by his wife Bonne of Artois, daughter of Philip of Artois, Count of Eu. John's elder brother, Charles I, Count of Nevers and Count of Rethel, had no legitimate children, and so on his death in 1464 his titles passed to John.
