The Flóabardagi (English: Battle of the Gulf) was a naval battle on June 25, 1244 off the coast of Iceland, in Húnaflói Bay, during the Sturlungaöld civil war. The conflicting parties were the followers of Þórður kakali Sighvatsson and those of Kolbeinn ungi Arnórsson. Þórður's men were from the Westfjords of Iceland, while Kolbeinn's were northerners. The primary weapons were hurled rocks between boats. A detailed description of the battle can be found in Sturlunga saga.
