The '''Siebenschneiderstein''' (''Söbenschniedersteen''<ref name=EG>[https://www.umweltkarten.mv-regierung.de/atlas/meta/boegen/bk/G2_068.pdf ''Findling Söbenschniederst.'' at www.umweltkarten.mv-regierung.de. Retrieved 20 Jun 2019.]</ref>) is a glacial erratic on the island of Rügen. It lies about 22 metres away from the cliffs of ''Gellort''<ref name=EG/> on the Baltic Sea beach, one kilometre northwest of Cape Arkona. It has a mass of 165 tonnes and a volume of 61 m<sup>3</sup>.<ref name=EG/> It belongs, like about 20 other erratics, to the legally protected geotopes on the Island of Rügen.
The rock is not the biggest erratic on Rügen (that is the Buskam at 600 m<sup>3</sup>), but it is the fourth largest and marks the northern point of the island and hence the northernmost point of Eastern Germany.
