Hrólfr Gautreksson was a legendary Geatish king who appears in Hrólfs saga Gautrekssonar and probably in Hyndluljóð.
Hrólfs saga Gautrekssonar tells that he was the son of king Gautrek and when his father died, his elder brother Ketill became king.
Hrólfr would court and finally win the Swedish king Erik's daughter Þornbjörg, who was a violent and proud ruler.
The names Þorir the Iron-Shield and Grímr shows that the lines probably refer to Þorir and Grímr Þorkelsson who appear with Hrólfr in Hrólfs saga Gautrekssonar.
