The fortification of Burggraf (German: Abschnittsbefestigung Burggraf), also called the Burggrafenstein or Furchste, is a levelled prehistorical or early medieval sector fortification on a hill spur between Untertrubach and Dörnhof near Gräfenberg in the county of Forchheim in the south German state of Bavaria.

The fortification was recorded in 1417 as a burgstall. It consisted of ramparts and an entrance passage at the southwest corner and probably a second on the southeast side. Only the remains of two sector ramparts have survived.
