Friedrich Heinrich von der Hagen (February 19, 1780 June 11, 1856) was a German philologist, chiefly distinguished for his researches in Old German literature. He was born at Angermünde-Schmiedeberg in the Uckermark region of the Margraviate of Brandenburg. After studying law at the University of Halle, he obtained a legal appointment in the state service at Berlin, but in 1806 resigned in order to devote himself exclusively to letters. In 1810 he was appointed professor extraordinarius of German literature at the University of Berlin in the following year he was transferred in a similar capacity to the University of Breslau, and in 1821 returned to Berlin as professor ordinarius. Although von der Hagen's critical work is now entirely out of date, he is credited with awakening an interest in old German poetry.
