The siege of Paris took place in 1590 during the French Wars of Religion when the French Royal Army under Henry of Navarre, and supported by the Huguenots, failed to capture the city of Paris from the Catholic League. Paris was finally relieved from the siege by an international Catholic and Spanish army under the command of Alexander Farnese, Duke of Parma.

Alexander Farnese (Italian: Alessandro Farnese, Spanish: Alejandro Farnesio; 27 August 1545 – 3 December 1592) was an Italian noble and condottiero and later a general of the Spanish army, who was Duke of Parma, Piacenza and Castro from 1586 to 1592, as well as Governor of the Spanish Netherlands from 1578 to 1592. Thanks to a steady influx of troops from Spain, during 1581–1587 Farnese captured more than thirty towns in the south (now Belgium) and returned them to the control of Catholic Spain. During the French Wars of Religion he relieved Paris for the Catholics. His talents as a field commander, strategist and organizer earned him the regard of his contemporaries and military historians as the first captain of his age.
