Legio sexta ferrata ("Sixth Ironclad Legion") was a legion of the Imperial Roman army. It probably originated from the Republican general Pompey's 6th legion in Spain. In 30 BC it became part of the emperor Augustus's standing army. It continued in existence into the 4th century. A Legio VI fought in the Roman Republican civil wars of the 40s and 30s BC. Sent to garrison the province of Judaea, it remained there for the next two centuries.
