The Devil in Love (French: Le Diable amoureux, 1772) is an occult romance by Jacques Cazotte which tells of a demon, or devil, who falls in love with a young Spanish nobleman[1] named Don Alvaro, an amateur human dabbler, and attempts, in the guise of a young woman, to win his affections.

[2] Canadian critic Carlo Testa has described The Devil In Love (in review of Stephen Sartarelli's 1993 translation) as a "terminus a quo" in the history of the demonic subgenre".

In the journey that unfolds, Satan, disguised as a woman, tries to seduce Alvaro who rejects his advances lest he lose his virginity.

He is unwilling to compromise his honor by sleeping with a woman before they are married and he will first need his mother’s approval of the union.

Lacan would adapt one scene from the story, in which the devil first appears and asks Alvaro "che vuoi?"
