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.
Having subjugated the Iberians and Albanians, Crassus then joined Antony's campaign against Parthia.
In the Battle of Actium in 31 BC, he commanded Antony's land forces against Octavian, having advised Antony before the battle that it would be more advantageous for their forces, together with those of Cleopatra, to fight on land, where they would have had the advantage over those of Octavian.
[2] [3] After Antony's defeat and flight to Egypt, Crassus was accused of deserting his army.
