Kloster Lüne (Lüne Abbey) is a medieval abbey in Lüneburg, in the German state of Lower Saxony. The abbey was founded in AD 1172 by a woman called Hildeswidis von Markboldestorp. It would appear that the monastic group was originally a chapter of canonesses and that it was not until about a hundred years later that it became a convent/abbey for Benedictine nuns.
