Venus in the Cloister or The Nun in her Smock, known in the original French as Vénus dans le cloître, ou la Religieuse en chemise (1683) is a work of erotic fiction by the Abbé du Prat, which is a pseudonym for an unknown author. Candidates for whom this might be include Jean Barrin (1640 in Rennes – 7/9/1718 in Nantes) and François de Chavigny de La Bretonnière.
