The Siege of Rheinberg 1586–1590, also known as the Capture of Rheinberg of 1590, took place at the strategic Cologne enclave of Rheinberg, one of the principal crossing-points over the Rhine on the stretch between the Electorate of Cologne and the Dutch border, between 13 August 1586 and 3 February 1590, during the Eighty Years' War, the Cologne War, and the Anglo-Spanish War.
