Spalahores, also spelled Spalohres or Spalahora, (Greek: Σπαλαχόρης Spalakhórēs; Σπαλύρις Spalýris,[1] ϹΠΑΛΥΡΙΟϹ Spalyrios (epigraphic); Kharosthi: 𐨭𐨿𐨤𐨫𐨱𐨆𐨪 Śpa-la-ho-ra, Śpalahora;[2] ruled circa 57-35 BCE), was an Iranian king who ruled Sakastan in the 1st-century BC.

Spalahores's name is attested on his coins in the Greek forms Spalakhórēs (Σπαλαχόρης) and Spalýris (Σπαλύρις),[1] and in the Kharosthi form Śpalahora (𐨭𐨿𐨤𐨫𐨱𐨆𐨪),[2] which are derived from the Saka name *Spalahaura, meaning "commander of the army".

Senior and Khodadad Rezakhani consider Spalahores and Spalirisos to indeed be Vonones' brothers,[5][6] while others such as K.W.

[9] Saghi Gazerani has suggested that after the Arsacid re-conquest of Sakastan (sometime between 124–115 BC), which was given as a fiefdom to the Surenid general that led the expedition, the Surenids (who became independent after 88 BC) and Sakas became closely connected, presumably through alliances and intermarriages.

[11] Spalahores' son and successor, Spalagadames, has been suggested by Rezakhani to be the same figure as the first Indo-Parthian king Gondophares (r. 19–46 CE).
