The Allegory of Love was the title of C.S. Lewis’s 1936 book about medieval and Renaissance literature.

The book examines the development of allegorical love poetry from the medieval period into the Renaissance. Lewis discusses writers and traditions that influenced Western ideas about courtly love, including poets such as Ovid, Chrétien de Troyes, and Edmund Spenser.

Its argument is literary rather than a general history of romantic relationships. Lewis traces how poets turned love into an elaborate symbolic and intellectual subject, especially through the conventions of courtly literature.

The work helped establish Lewis as a major literary scholar before he became best known to many readers for Christian apologetics and imaginative fiction. It also reflects his lasting interest in medieval texts and literary history.
