Hnabi or Nebi was an Alemannic duke in the eighth century. He was a son of Huoching and perhaps a grandson of the duke Gotfrid, which would make him a scion of the Agilolfing dynasty of Bavaria. He himself was the founder of the "old" line of the Ahalolfings.
Around 724 he was one of the joint founders of the monastery of Reichenau.
