Dietrich und Wenezlan (Dietrich and Wenezlan) is a fragmentary Middle High German poem about the legendary hero Dietrich von Bern, the counterpart of the historical Ostrogothic king Theodoric the Great in Germanic heroic legend. It usually considered part of the so-called "historical" Dietrich material, as it appears to cite Dietrich's exile at the court of Etzel described in the "historical poems" Dietrichs Flucht and the Rabenschlacht. The fragment of about 500 lines tells of Dietrich's challenge by Wenezlan of Poland, who has captured one of Dietrich's warriors. It is unclear whether the fragment was the main focus of a poem or a single episode from a longer poem.
