Blondel de Nesle – either Jean I of Nesle (c. 1155 – 1202) or his son Jean II of Nesle (died 1241) – was a French trouvère. The name 'Blondel de Nesle' is attached to twenty-four or twenty-five courtly songs. If the works are correctly identified and dated, he was a significant influence on his European contemporaries, who made much use of his melodies. His works are fairly conventional, and several have been recorded in modern times.
