Publius Canidius Crassus (died 30 BC) was a Roman general and Mark Antony's lieutenant. He served under Lepidus in southern Gallia in 43 BC, and was henceforth allied with Antony. He became suffect consul in 40 BC and then served as a commander in Armenia whence he invaded, in 36 BC, Iberia (Georgia), and forced its king Pharnabazus into alliance against Zober, king of Albania. Having subjugated the Iberians and Albanians, Crassus then joined Antony's campaign against Parthia.
