was the daughter of Agnes and Berthold, duke of Carinthia. She married Henry, duke of Poland and Silesia, by whom she had three sons and three daughters. They afterwards made a vow of chastity, Henry becoming priest and subsequently bishop, while Hedwig entered a Cistercian convent near Trebnitz, without, however, taking the veil. She died there October 15, 1243, and was buried in the convent. She was canonized by pope Clement IV in 1267 (or 1268). She is commemorated on the 17th of October.
