The Kings or Judges of Arborea (from the Latin Latin: iudices and the Sardinian Sardinian: judikes, "judges", the title of the Byzantine officials left behind when imperial power receded in the West) were the local rulers of Arborea in the west of Sardinia during the Middle Ages. Theirs was the longest-lasting judgedom, surviving as an independent state until the fifteenth century.

Arborea underwent a succession crisis following the death of Marianus V. William, a great grandson of Marianus IV, was crowned king in 1409, but, unable to assert his claim by force, sold the title to Martin of Aragon in 1420. The following were titular rulers.
Rights passed to the House of Alagona, lords of Sastago and Pina, whom the Aragonese deposed as a result of the revolt.
