The Battle of Valenciennes was fought on 16 July 1656 between the Spanish troops commanded by John Joseph of Austria and the French troops under Henri de la Tour d'Auvergne, Vicomte de Turenne, in the outskirts of the city of Valenciennes in the Spanish Netherlands during the Franco-Spanish War. After a period of Spanish recovery following the Peace of Münster in 1648, France went again on the offensive in 1654, having succeeded in suppressing internal rebellions, and took several towns in the province of Hainaut over the course of two years. On early 1656, Turenne was instructed by the French court to continue the offensive. He intended at first to besiege Tournai, but realising that it had been strongly reinforced by the Army of Flanders under the newly appointed John Joseph of Austria, illegitimate son of Philip IV of Spain, he went instead to besiege Valenciennes, in the course of the Scheldt River.

John Joseph of Austria or John of Austria (the Younger) (Spanish: Don Juan José de Austria; 7 April 1629 – 17 September 1679) was a Spanish general and political figure. He was the only illegitimate son of Philip IV of Spain to be acknowledged by the King and trained for military command and political administration. Don John advanced the causes of the Spanish Crown militarily and diplomatically at Naples, Sicily, Catalonia, the Netherlands, Portugal, Dunkirk, and other fronts. He was the governor of the Southern Netherlands from 1656 to 1659. He remained a popular hero even as the fortunes of Imperial Spain began to decline. His feuds with his father's widow, Queen Mariana of Austria, led to a 1677 palace coup through which he exiled Mariana and took control of the monarchy of his half-brother Charles II of Spain. However, he proved far from the saviour Spain had hoped he would be. He remained in power until his death in 1679.
