Hrœrekr Ringslinger or Ringscatterer, Old Icelandic: Hrærekr slöngvanbaugi, Old Danish: Rørik Slængeborræ or Rørik Slyngebond was a legendary 7th century king of Zealand or Denmark, who appears in Chronicon Lethrense, Annals of Lund, Gesta Danorum, Sögubrot, Njál's saga and in Hversu Noregr byggdist.

Beside the name, the Danish and the West Norse traditions have little more in common than his living a few generations after Hrólfr kraki, his name and his title. He may be most notable as the grand-father of Hamlet.

The name Slængeborræ, in Chronicon lethrense and the Annals of Lund is a corruption of Slænganbøghe, which is the Old East Norse form of Old West Norse slöngvanbaugi meaning "ring slinger", i.e. a king who was generous with his gold. Saxo's version Slyngebond means "bracelet slinger" and the motivation Saxo gives is strikingly different.

In the Danish tradition Rørik is the son of an earthly Höðr, and notably the grand-father of Hamlet. Rørik is described a powerful king of Denmark.

The Chronicon lethrense and the Annals of Lund make Rørik the son of an earthly Höðr who killed Balder, Odin's son in battle. Höðr was himself killed by Odin's son Both.

Rørik Slængeborræ was a victorious king who conquered Courland, Wendland and Sweden and made them pay tribute to him. He appointed Orwendel and Feng as the commanders of Jutland and gave his sister to Orwendel. The sister and Orwendel were the parents of Amblothe (Hamlet). Rørik was succeeded by Wighlek.

The Norwegian and Icelandic tradition only mentions Hrœrekr in relation to the Scanian chieftain Ivar Vidfamne who made himself the ruler of both Denmark and Sweden. There is no information on his parentage, nor any Hamlet. In these sources, Hrœrekr is only the king of Zealand, Skåne and Jutland being in the hands of other rulers.
