John II, Count of Nevers (fr. Jean de Nevers , 1415–1491), known as John of Clamecy prior to acquiring titles, was a French nobleman and the last male member of the House of Valois-Burgundy. He was initially Count of Étampes from 1442 to 1465, and later became Count of Nevers and Rethel from 1464, and also Count of Eu from 1472. Since John had no male heirs, his counties of Nevers and Eu were inherited by his grandson Engelbert of Cleves, son of John's older daughter Elizabeth of Nevers (d. 1483), while the County of Rethel was inherited by John's younger daughter Charlotte (d. 1500).
