Frederick (1377–1387) was the Judge of Arborea from 1383 until his death. His surname was Doria, but since he belonged to the ruling house of Arborea he is often dynastically called Bas-Serra, or Doria-Bas. Nephew and successor of Hugh III, he was a minor upon his succession and was under the tutelage of his mother Eleanor.
