David Arianites or Areianites () was a high-ranking Byzantine commander of the early 11th century. The origin of the surname is uncertain and different theories have been proposed ranging from various anthroponomastic and toponymic derivations of the Indo-European word arya to the name of a minor Illyrian tribe the Arinistae/Armistae. The family is hence variously considered to have been of possibly Albanian or Iranian origin. David is generally considered to be the first member of the Arianiti clan active in late medieval Albania, but the connection can't be verified due to lack of sources.
