Herman VI, Margrave of Baden (died October 4, 1250) was nominally Duke of Austria and Styria. In 1248, he married Gertrud, the niece of the last male member of the Babenberg family, Duke Frederick II of Austria. She brought the Duchies of Austria and Styria as her heirloom. However, Herman and his son Frederick could not establish themselves in Austria.
