Charles d’Espinay (c. 1531, château d’Espinay – September 1591, Epiniac) was a French cleric, bishop and poet. He is most notable for his sonnets, particularly his erotic “Sonnets amoureux” published in 1559-1560 – he was a contemporary and disciple of Pierre de Ronsard.
He was the younger son of Guy III d’Espinay († 1551) and his wife Louise de Goulaine. His elder brother Jean II († 1591) became a marquis in 1575 and continued the family line. They also had other siblings – Philippine, who became abbess of abbaye Saint-Georges de Rennes (1572-1583), and Louis d’Espinay († 1600), commendatory to abbaye Notre-Dame du Tronchet (1558-1567) before marrying and becoming lord of Yvigniac. Louis’ son Jean d’Espinay became abbot commendatory to the abbaye de Saint-Méen (1592-1604).
