Sögubrot af nokkrum fornkonungum
Sögubrot af nokkrum fornkonungum í Dana- ok Svíaveldi ("Fragment of a Saga about Certain Ancient Kings in the Commonwealth of the Danes and Swedes", often abbreviated to Sögubrot or Sögubrot af fornkonungum) is a fragmentary Old Icelandic text dealing with some legendary Swedish and Danish kings. It is thought to be a part of a younger redaction of the lost Skjöldunga saga.
