Legio II Parthica ("Parthian-conquering Second Legion") was a legion of the Imperial Roman army founded in AD 197 by the emperor Septimius Severus (r. 193–211), for his campaign against the Parthian Empire, hence the cognomen Parthica. The legion was still active in the beginning of the 5th century. The legion's symbol was a centaur.
