Asclepiodotus Tacticus was a Greek author of the 1st century BCE. He is known only as the writer of a military treatise. The Suda identifies an Asclepiodotus as a student of the Stoic philosopher Posidonius, an identification generally accepted for the tactical writer. This places him within late Hellenistic intellectual circles, likely on Rhodes. No further biographical details survive.

His sole extant work is the Tactica, a systematic treatise on Hellenistic military theory. This concise manual methodically details the organization, formations, drills, and signals of a Macedonian-style army. Asclepiodotus’s significance lies in his preservation and clear systematization of Hellenistic military science. His work provides a valuable snapshot of pre-Roman imperial military theory and was used by later Byzantine writers. He is part of the tradition of Greek tactical writers between Aeneas Tacticus and Arrian.
