Heden, Hedan, or Hetan II (died 741), called the Younger, was a Duke of Thuringia, one of the "older" stem duchies (Stammesherzogtums), from around 700 until his death.
Only under Hedan did the duke take up an extensive interest in the lands to the east, the region today called Thuringia.
It was during the reign of Hedan that the conversion of the Thuringii to Christianity, abortively initiated by Kilian, began to bear fruit under Boniface.
In a donation dated 1 May 704 in Würzburg, his capital, Hedan, with the consent of his wife and his son Thuring and the Frankish magnates Rocco and Doda, granted the bishop Willibrord the places of Arnstadt (Arnestati), Mühlberg (Mulenberge), and Großmonra (Monhore).
A document dated 18 April 716/717, Hedan enlarged his earlier donation by granting hereditary estates on the Saale and at Hammelburg (on the Saale) to the counts Cato and Sigeric as well as the nutricius (tutor or regent) Ado and the magnates Adogoto and Hereric.
