René Rapin (1621–1687) was a French Jesuit and writer. He was born at Tours and entered the Society of Jesus in 1639. He taught rhetoric, and wrote extensively both in verse and prose. His first production, Eclogæ Sacræ (Paris, 1659), won him the title of the Second Theocritus, and his poem on gardens, Hortorum libri IV (Paris, 1665), twice translated into English (London, 1673; Cambridge, 1706), placed him among the foremost Latin versifiers. Of his critical essays, the best known are: Observations sur les poèmes d'Homère et de Virgile (Paris, 1669); Réflexions sur l'usage de l'éloquence de ce temps (Paris, 1672); Réflexions sur la poétique d'Aristote et sur les ouvrages des poétes anciens et modernes (Paris, 1674).
