Hunald II, also spelled Hunold, Hunoald, Hunuald or Chunoald, was the Duke of Aquitaine from 768 until 769. He was probably the son of Duke Waiofar, who was assassinated on the orders of King Pippin the Short in 768. He laid claim to the duchy following Pippin's death later that year, but his revolt was crushed by Pippin's eldest son, Charlemagne. Hunald fled to the Duchy of Gascony, but he was handed over to Charlemagne and put into captivity. Nothing more is heard of him.
