阿希达穆斯五世 Αρχιδαμος Ε' （活动时间前3世纪）欧里庞提德世系的第31代斯巴达国王（约前227年在位）。

阿希达穆斯五世为斯巴达国王欧达米达斯二世之子，阿希达穆斯四世之孙。他是著名的改革者亚基斯四世的弟弟。前241年亚基斯四世被五人议事会谋杀后，阿希达穆斯五世逃往美塞尼亚避难。前227年，另一位锐意改革的斯巴达国王克里昂米尼三世（属亚基亚德世系）因缺一共同在位者而将他召回。但阿希达穆斯五世回国后不久即被谋杀。古典作家对此有不同解释：波里比阿认为凶手是克里昂米尼三世，而希罗多德则归咎于反对改革的政治集团。

Archidamus V (Ancient Greek: Ἀρχίδαμος Ε΄) was the 27th of the Kings of Sparta of the Eurypontid line, reigning in 228–227 BC.

He was the son of Eudamidas II and Agesistrata and through him the grandson of Archidamus IV, after whom he was named.

After his brother Agis IV was murdered in 241 BC, he fled to Messenia. In 228 (or 227) he was ordered back to Sparta by King Cleomenes III of the Agiad line, who had no counterpart on the throne by then, after the death of Eudamidas III, the son of Agis IV. He was assassinated shortly afterwards. Polybius claims that he was killed by Cleomenes.
