Fljótsdæla saga (listen^ⓘ) is one of the Icelandic sagas. It was probably the last one written, perhaps from the 1400s or 1500s. The text is known from several manuscripts which are from the early 1600s. It was probably written by an author in the east of Iceland and is a sequel to Hrafnkels saga. ^{[1] [2]}

The saga revolves around the lives and times of the residents of the Fljótsdalur region in Iceland, including Helge Åsbjørnsson (Helgi Ásbjarnarson) and of Grim (Grímr) and Helge (Helgi), two sons of the widow Droplaug, a pair of brothers who have their own saga, Droplaugarsona saga.^{[3] [4]}
