Jean-Baptiste Henri de Trousset, lord of Valincour or Valincourt (1 March 1653, Paris – 4 January 1730) was a French admiral and man of letters. He was a friend of chancellor d'Aguesseau, Racine (who he replaced at Académie française and as official historiographer to Louis XIV) and Boileau (Valincour was the dedicatee of Boileau's eleventh satire, "On true and false honour", and also completed the publication of Boileau's works in 1713).
