Ludgarda (c. 1260/61 – bef. 14 December 1283), was a German noblewoman of the House of Mecklenburg, and by marriage Duchess consort of Poznań during 1273–1283 and of all Greater Poland during 1279–1283.
She was the eldest child and only daughter[1] of Henry I the Pilgrim, Lord of Mecklenburg by his wife Anastasia, daughter of Barnim I, Duke of Pomerania. She was probably named after her paternal grandmother, Luitgard of Henneberg.[2]
