Der arme Heinrich is a Middle High German narrative poem by Hartmann von Aue. It was probably written in the 1190s and was the second to last of Hartmann's four epic works. Combining courtly and religious narrative patterns, it tells the story of a noble knight who has been stricken by God with leprosy and can be cured only by the heart's blood of a virgin who willingly sacrifices herself for his salvation.

Hartmann von Aue, also known as Hartmann von Ouwe, was a German knight and poet. With his works including Erec, Iwein, Gregorius, and Der arme Heinrich, he introduced the Arthurian romance into German literature and, with Wolfram von Eschenbach and Gottfried von Strassburg, was one of the three great epic poets of Middle High German literature.
