The Siege of Venlo of 1586, also known as the Capture of Venlo, was a Spanish victory that took place on June 28, 1586, at the city of Venlo, in the southeastern of Low Countries, near the German border (present-day Province of Limburg, the Netherlands), between the Spanish forces commanded by Governor-General Don Alexander Farnese, Prince of Parma (Spanish: Alejandro Farnesio), and the Dutch garrison of Venlo, supported by relief troops under Maarten Schenck van Nydeggen and Sir Roger Williams, during the Eighty Years' War and the Anglo-Spanish War (1585–1604). After two failed attempts to relieve the city, the siege ended on June 28, 1586, with the capitulation and the withdrawal of the Dutch garrison.
