Droplaugarsona saga () is one of the Icelanders' sagas, probably written in the 13th century. The saga takes place near Lagarfljót in the east of Iceland about 1000 AD.
It tells the story of GrÃÂmr and Helgi, sons of the widow Droplaug, as grown men. Helgi is killed by Helgi ÃÂsbjarnarsson. GrÃÂmr avenges his brother's death by killing Helgi ÃÂsbjarnarsson. These are the same brothers who also appear in Fljótsdæla saga. Some of the storyline of Droplaugarsona saga overlaps with that of Fljótsdæla saga, although details often differ.
