Jutta of Kulmsee was a 13th-century German noblewoman who became a Franciscan tertiary and an anchoress. Born into the noble Sangerhausen family, she initially lived as a married woman before dedicating her life to poverty and service. Following the example of Elizabeth of Hungary, she renounced her status to care for the sick, the blind, and lepers. She eventually sought enclosure in a cell near Kulmsee, where she lived as a contemplative, focusing her prayers on the conversion of people in Prussia.
