The siege of Málaga (1487) was an action during the Reconquest of Spain in which the Catholic Monarchs of Spain conquered the city of Mālaqa from the Emirate of Granada. The siege lasted about four months.

It was the first conflict in which ambulances, or dedicated vehicles for the purpose of carrying injured persons, were used. Geopolitically, the loss of the emirate's second largest city—after Granada itself—and its most important port was a major loss for Granada. Most of the surviving population of the city were enslaved or put to death by the conquerors.
