The Letters of a Portuguese Nun (French: Les Lettres Portugaises, literally The Portuguese Letters), first published anonymously by Claude Barbin in Paris in 1669, is a work believed by most scholars to be epistolary fiction in the form of five letters written by Gabriel-Joseph de La Vergne, comte de Guilleragues (1628–1684), a minor peer, diplomat, secretary to the Prince of Conti, and friend of Madame de Sévigné, the poet Boileau, and the dramatist Jean Racine.
