The siege of Heidelberg or the Imperial-Spanish capture of Heildelberg took place from 23 July to 19 September 1622, at Heidelberg, Electorate of the Palatinate, between the Imperial-Spanish army led by Johan Tzerclaes, Count of Tilly and Don Gonzalo Fernández de Córdoba against the Anglo-Protestant forces of Frederick V, Elector Palatine, commanded by Sir Gerard Herbert and Sir Horace Vere during the Palatinate campaign, in the context of the Thirty Years' War. On 16 September the city of Heidelberg was taken by storm, and the Heidelberg Castle surrendered three days later to the Imperial and Spanish forces.
