Acestor (Ancient Greek: Ἀκέστωρ), meaning "healer" or "saviour", was the name of several figures in Classical mythology and history:

Mythological

• Apollo Acestor, an epithet of the god Apollo in his role as healer or averter of evil.^[1][2]
• Acestor, son of Ephippus, son of Poemander from Tanagra in Boeotia. He was killed by Achilles during the Trojan War.^[3]

Historical

• Acestor, Cretan sculptor.

• Acestor Sacas, surnamed "Sacas" (Σάκας) on account of his foreign origin, was a tragic poet at Athens, and a contemporary of Aristophanes. He seems to have been either of Thracian or Mysian origin.^{[4][5][6][7][8]}

• Acestor, a sculptor mentioned by Pausanias as having executed a statue of Alexibius,^[9] a native of Heraea in Arcadia, who had gained a victory in the pentathlon at the Olympic Games. He was born at Knossos, or at any rate exercised his profession there for some time.^[10] He had a son named Amphion, who was also a sculptor, and had studied under Ptolichus of Corcyra;^[11] so that Acestor must have been a contemporary of the latter, who flourished around Olympiad 82 (452 BC).^[12]
