Pierre Petit (French: [pəti]; 1617–1687) was a French scholar, physician, poet and Latin writer. Born at Paris, Petit studied medicine at Montpellier, where he took the degree of MD, though he did not practice medicine afterwards. Returning to Paris, he resided for some time with the president Lamoignon, as tutor to his sons, and afterwards as a literary companion with Aymar de Nicolai, first president of the chamber of accounts. He died shortly after taking a wife.
