The Battle of Poimanenon or Poemanenum was fought in early 1224 (or possibly late 1223) between the forces of the two main successor states of the Byzantine Empire; the Latin Empire and the Byzantine Greek Empire of Nicaea. The opposing forces met at Poimanenon, south of Cyzicus in Mysia, near Lake Kuş.
