Clitomachus (Greek: Κλειτόμαχος, also Cleitomachus or Kleitomachos; 187/6–110/09 BC) originally named Hasdrubal, was a Carthaginian who came to Athens in 163/2 BC and studied philosophy under Carneades. He became head of the Academy around 127/6 BC. He was an Academic skeptic like his master. Nothing survives of his writings, which were dedicated to making known the views of Carneades, but Cicero made use of them for some of his works.
Clitomachus was born in Carthage in 187/6 BC, and he was originally named Hasdrubal. He came to Athens in 163/2 BC, when he was about 24 years old. He there became connected with the founder of the New Academy, the philosopher Carneades, under whose guidance he rose to be one of the most distinguished disciples of this school; but he also studied at the same time the philosophy of the Stoics and Peripatetics. In 127/6 BC, two years after the death of Carneades, he became the effective head (scholarch) of the Academy. He continued to teach at Athens till as late as 111 BC, as Crassus heard him in that year. He died in 110/09 BC, and was succeeded as scholarch by Philo of Larissa.
Of his works, which amounted to 400 books, only a few titles are preserved. His main object in writing them was to make known the philosophy of his master Carneades, from whose views he never dissented. Clitomachus continued to reside at Athens till the end of his life; but he continued to cherish a strong affection for his native country, and when Carthage was taken in 146 BC, he wrote a work to console his unfortunate countrymen. This work, which Cicero says he had read, was taken from a discourse of Carneades, and was intended to exhibit the consolation which philosophy supplies even under the greatest calamities. His work was highly regarded by Cicero, who based parts of his De Natura, De Divinatione and De Fato on a work of Clitomachus he names as On the Withholding of Assent (Latin: De Sustinendis Offensionibus).
Two of Clitomachus' works are known to have been dedicated to prominent Romans, the poet Gaius Lucilius and the one-time consul Lucius Marcius Censorinus, suggesting that his work was known and appreciated in Rome.

Diogenes Laërtius, iv 67, however, writes that he "had reached his fortieth year when he went to Athens", but this is, according to Woldemar Görler Die Akademie zwischen Karneades und Philon (in Grundriss der Geschichte der Philosophie, Die Philosophie der Antike, Bd. 4/2: Die hellenistische Philosophie, hrsg.
