Baltazar de Cordes (16th century– 3 January 1601), the brother of Simon de Cordes, was a Dutch corsair who fought against the Spanish Empire during the early 17th century.
Born in the Netherlands in the mid-16th century, Cordes began sailing for the Netherlands against Spain during the Eighty Years' War. Baltazar possibly arrived in the Pacific during the 1598 Magellano Company expedition attempting to circumnavigate South America. This expedition, under the command of Admiral Jacques Mahu, consisted of five ships. One of the vessels, the Liefde ("Love" or "Charity"), reached Japan in 1600, pilot William Adams among the surviving crew. He succeeded Captain Jurriaan van Bokholt (or Van Boekhout) who died around August 23, 1599 shortly after crossing the Straits of Magellan.
