Audun Hugleiksson (Hestakorn) ( 1240 – 2 December 1302) was a Norwegian nobleman at the end of the 13th century. He was the king's right hand, both under King Magnus Lagabøte and King Eirik Magnusson, and was seen as an important politician and lawman in his time. He played a central role in reforming the Norwegian law system. From 1280 and onwards he was given increasingly important roles in the government of Norway. He had his own seat on the king's council, was a lawyer (stallare), tax minister (fehirde) and a baron. He also erected a castle or fortress in stone called Audunborg on Ålhus in Jølster in Sunnfjord.
