  Duchy of Łęczyca (Polish: Księstwo łęczyckie) was one of the duchies of Poland. It was created around 1231 from the Seniorate Province by Konrad I of Masovia. In 1264 the Duchy of Sieradz was split from it. The last duke of this duchy was Władysław the Hunchback. After his death in 1352 the duchy became part of the Kingdom of Poland and was reorganized into the Łęczyca Voivodeship.
