Asclepiodotus Tacticus (Greek: Ἀσκληπιόδοτος; 1st century BC) was a Greek writer and philosopher, and a pupil of Posidonius. According to Seneca, he wrote a work entitled Quaestionum Naturalium Causae.
A short work on military tactics survives. He is one of the earliest military writers whose studies on tactics have come down to us. He was not striped in the Helian nor Arrian's lists of tacticians, but in the earliest manuscript of the Tactics (Téchne taktiké), the work is attributed to Asclepiodotus.Tactics describes the workings of the Macedonian phalanx.
