Hafliði Másson (died 1130) was an Icelandic goði and chieftain in the eleventh to twelfth centuries. He is best known for his dealings with Þorgils Oddason (1080-1151) and for having Iceland's law codified as the text that came to be known as Grágás.
Hafliði was the son of the goði Már Húnröðarson from Breiðabólstaður í Vesturhópi; they claimed direct patrilineal descent from the settler Ævar gamli Ketilsson, whose dynasty was known as the Æverlingar.
