Henri de Gauchy (also spelled Gauchi, ) was a French magister and canon of Saint-Martin de Liège in the late 13th century.Laurent Brun (2020), "Henri de Gauchy", Archives de littérature du Moyen Âge (ARLIMA).

In 1282, at the request of King Philip IV of France, Henri translated the De regimine principum of Giles of Rome from Latin into French under the title Le livre du gouvernement des rois et des princes ('the book of the government of the kings and of the princes'). Giles's work was, with the Secretum Secretorum, the most popular work in the mirror for princes genre during the Middle Ages.Charles F. Briggs (1993), "Manuscripts of Giles of Rome's De regimine principum in England, 1300–1500: A Handlist", Scriptorium 47(1): 60–73. Henri's translation is preserved complete in at least 30 manuscripts and in part in at least nine more.Gavino Scala (2021), La tradizione manoscritta del "Livre du gouvernement des roys et des princes" di Henri de Gauchy: Studio filologico e saggio di edizione (PhD dissertation, University of Zurich), pp. 27–29, contains a list.

Henri's translation, if not Giles's original, may have been the main source for the vernacular Venetian Trattato de regimine rectoris of Paolino Veneto.Suzanne Mariko Miller (2007), Venice in the East Adriatic: Experiences and Experiments in Colonial Rule in Dalmatia and Istria (c. 1150–1358) (PhD dissertation, Stanford University), p. 150.
