André Dacier (6 April 1651 - 18 September 1722), was a French classical scholar.

He was born at Castres in upper Languedoc. His father, a Protestant lawyer, sent him first to the academy of Puy Laurens , and afterwards to Saumur to study under Tanneguy Lefebvre. On Lefebvre's death in 1672, Dacier moved to Paris, and was appointed one of the editors of the Deiphin series of the classics. In 1683 he married, Anne Lefèvre, the daughter of his old tutor. Better known by her married name of Madame Dacier, she was also a learned translator of the classics.

In 1695 he was elected to the Academy of Inscriptions, and also to the Académie française; not long after this, as payment for his share in the medallic history of the king's reign, he was appointed keeper of the library of the Louvre. He died two years after his wife.

The most important of his works were his editions of Pompeius Festus and Verrius Flaccus, and his translations of Horace (with, notes), Aristotle's Poetics, the Electra and Oedipus Coloneus of Sophocles, Epictetus, Hippocrates and Plutarch's Lives.
