Aulus Caecina Alienus, Roman general, was quaestor of Hispania Baetica (southern Iberia) in AD 68. On the death of Nero, he attached himself to Galba, who appointed him to the command of a legion in upper Germany. Having been prosecuted for embezzling public money, Caecina went over to Vitellius, who sent him with a large army into Italy. Caecina crossed the Alps, but was defeated near Cremona by Suetonius Paulinus, the chief general of Otho. Subsequently, in conjunction with Fabius Valens, Caecina defeated Otho at the decisive battle of Bedriacum (Betriacum).
