Gaius Laelius Sapiens (born c. 188 BC), was a Roman statesman, best known for his friendship with the Roman general and statesman Scipio Aemilianus (Scipio the Younger) (d. 129 BC). He was consul of 140 BC, elected with the help of his friend, by then censor, after failing to be elected in 141 BC. Gaius Laelius Sapiens was the son and heir of the Punic War general Gaius Laelius, himself consul in 190 BC. This Laelius had been former second-in-command and long-time friend, since childhood, of the Roman general and statesman Scipio Africanus. The younger Laelius was apparently born around 188 BC, after his father had become consul but had failed to win command of the campaign against Antiochus III the Great of Syria, which would have made him a rich man. His mother's name is unknown.
