Heinrich III von Gleichenstein

Heinrich III von Gleichenstein (died 1299) was the last count of the Gleichenstein branch in the Eichsfeld. His comital house had fallen deep into debt.

In 1294 it sold its Eichsfeld estates and castles to the Archbishopric of Mainz, and its Vogtei rights were also sold to Mainz that year. With Heinrich's death in 1299 the Gleichenstein line died out.
