Heinrich von Plauen (the Elder) (ca. 1370–1429) was the 27th Grand Master of the Teutonic Knights, serving from November 1410 to October 1413. He is famous for saving Castle Marienburg after the Order's defeat in the Battle of Grunwald (Tannenberg) in 1410. He wanted to continue war with Poland and for that reason was removed from the office by Michael Küchmeister von Sternberg. Because all male members of his family were baptized as Heinrich (Henry), he is sometimes known as Heinrich von Plauen the Elder to differentiate from his relative, Heinrich von Plauen the Younger (died ca. 1441).
