Guy II de Nesle (died August 14, 1352), Lord of Mello, was a Marshal of France (1348) who was killed in the Battle of Mauron.
In 1352, Nesle was co-founder, with King John II of France, of the newly created Order of the Star.
In August of that same year, Nesle led a contingent of some hundred Knights of the Order into Brittany.
The entire force was killed, which dealt a serious blow to survival of the Order of the Star.
His brother Guillaume, as well as his cousin Jean de Clermont (who was made Marshal of France in 1352), were killed in the Battle of Poitiers (1356).
