French humanist and classical scholar, celebrated for the elegance of his Latin prose style.

From age 18 Muret taught classics at various schools; Michel de Montaigne was among his pupils. During the 1540s his play Julius Caesar, written in Latin, was performed; it is the first tragedy on a secular theme known to have been written in France. In the early 1550s he lectured on philosophy and civil law in Paris. He became intimate with the poets of La Pléiade, and in 1553 he published a commentary on Pierre de Ronsard's Les Amours. Juvenilia, a collection of Muret's own poems, many of them on erotic themes, was published at about the same time. In 1554, after being condemned for sodomy and heresy, Muret fled to Italy, settling in Rome in 1563. His lectures at the University of Rome earned him a European reputation. He entered holy orders in 1576.

Muret was a good textual critic; his Variae lectiones contains annotations and expositions of many passages from ancient authors. He also wrote commentaries on works by Cicero, Catullus, Tacitus, Plato, and Aristotle.
