Cossus Cornelius Lentulus was a Roman senator, who was active during the reign of Tiberius. He was consul in the year AD 25 as the colleague of Marcus Asinius Agrippa.[1] Except for his consulship, the only office Lentulus might have held is governorship of Germania Superior, as Edmund Groag conjectured.[2]
Lentulus was the son of Cossus Cornelius Lentulus Gaetulicus, consul in 1 BC. His brother was Gnaeus Cornelius Lentulus Gaetulicus, consul in the year 26. He is known to have a son, Cossus Cornelius Lentulus, consul in the year 60, as the colleague of Nero.[3]
