The Siege of Gravelines, May to July 1644, took place during the 1635–1659 Franco-Spanish War. A French army captured the port of Gravelines, then in the Spanish Netherlands, now the Pas-de-Calais region of northern France. Siege operations began on 28 May 1644 and the town surrendered on 28 July. Recaptured by the Spanish in 1652, it changed hands again in 1658 before being ceded to France permanently in the 1659 Treaty of the Pyrenees.
