Adelheid Langmann (born 1306 in Nuremberg; died November 22, 1375, in Engelthal) was a nun and mystic in the Dominican convent of Engelthal near Nuremberg. Adelheid Langmann was the daughter of the Nuremberg councilor Otto Langmann and his wife Mechthild, who later became a nun herself in 1350. At the age of 13, Adelheid was betrothed to Gottfried Teufel, who soon passed away shortly after their wedding. Before 1330, Adelheid entered the convent of Engelthal against the wishes of her family and her initial resistance.
