Pierre de Melun (died 1594), prince of Espinoy, marquis of Richebourg, baron of Antoing, etc., was a nobleman in the Low Countries during the Dutch Revolt who took the side of the rebels against Philip II of Spain.
Melun was born in the first half of the 16th century, probably in Antoing, the son and heir of Hugues, count of Epinoy, and Yolande, lady of Warchin.
In 1577 he was declared a rebel and his properties in the Low Countries were confiscated by the crown and awarded to his younger brother, Robert de Melun.
On 10 February 1582, Melun was among the nobles who greeted Francis, Duke of Anjou, on his return from England with the intention of proclaiming him sovereign of the Low Countries.
After his death his son, Guillaume de Melun, with diplomatic support from Henry IV of France,[2] sought to recover at least some of his confiscated inheritance, reaching an agreement that was ratified by the government of the Sovereign Archdukes Albert and Isabella on 16 August 1602.
