The Magnificent Cuckold or Il magnifico cornuto is a 1964 Italian sex comedy film directed by Antonio Pietrangeli and based on the Belgian play Le Cocu magnifique written by Fernand Crommelynck.

The Magnificent Cuckold is about a hat tycoon who is ecstatically, if not hungrily, in love with his youthful wife.

It is all blissful, that is, until our man, middle-aged and somewhat of a square among his blasé, upper-class friends to whom cuckoldry is a common practice, is seduced by one of them.

Gnawed by jealously, he will imagine variations on catching her and her lover red-handed.

The New York Times published a positive, detailed review and stated Il magnifico cornuto was "mildy amusing".
