Legio IV Scythica, also written as Legio IIII Scythica, was a legion of the Imperial Roman army founded in c. 42 BCE by the Roman general Mark Antony, for his campaign against the Parthian Empire, hence its other cognomen, Parthica. The legion was still active in the Roman province of Syria in the early 5th century.
