Neidhart von Reuental (Middle High German: Nîthart von Riuwental; also Her Nîthart; possibly born c. 1190 – died after 1236 or 1237) was one of the most famous German minnesingers. He was probably active in the Duchy of Bavaria and then is known to have been a singer at the court of Duke Frederick II of Austria in Vienna. As a minnesinger he was most active from 1210 to at least 1236.
Neidhart is very well known for being rather sarcastic and comical. More melodies survive by him than from any other minnesinger.
He was mentioned in a passage of Wolfram von Eschenbach's Willehalm poem written before 1217, when Neidhart had already achieved a certain degree of fame. All manuscript sources until the 15th century refer to him only as "Nithart". The origin of the name it self is Nithard, Altniederfränkisch and the meaning is hard in hostility. With time and expanded geographical use, the spelling has changed and the meaning eventually being confused when interpreted in modern German. His name has before been believed to be an allegorical pseudonym, for its meaning could be interpreted more or less as Grim-Heart of Lament-Valley. The second part of his name, was created by philologists of the 19th century, who took literally the role of the "speaker," who calls himself "von Reuental" in his poems, and thus combined it with the author's name, which was simply "Nîthart".
His earlier poetry referred to places in the Bavarian and Salzburg region, while later he called the Austrian duke Frederick II his patron. He mentions a residence at Lengbach near Tulln, west of Vienna. His tomb, probably erected at the behest of Duke Rudolf IV of Austria (1339–1365), is preserved on the south side of St. Stephen's Cathedral.
