Old French (franceis, françois, romanz; Modern French ancien français) was the Gallo-Romance dialect continuum spoken from the 9th century to the 14th century. In the 14th century, these dialects came to be collectively known as the langues d'oïl, contrasting with the langue d'oc or Occitan language in the south of France. The mid-14th century is taken as the transitional period to Middle French, the language of the French Renaissance, specifically based on the dialect of the Île-de-France region.

The place and area where Old French was spoken natively roughly extended to the historical Kingdom of France and its vassals (including parts of the Angevin Empire, which during the 12th century remained under Anglo-Norman rule), and Burgundy, Lorraine and Savoy to the east (corresponding to modern north-central France, Belgian Wallonia, western Switzerland and northwestern Italy), but the influence of Old French was much wider, as it was carried to England, Sicily and the Crusader states as the language of a feudal elite and of commerce.

The areal of Old French in contemporary terms corresponded to the northern parts of the Kingdom of France (including Anjou and Normandy, which in the 12th century were ruled by the Plantagenet kings of England), Upper Burgundy and the duchy of Lorraine. The Norman dialect was also spread to England and Ireland, and during the crusades, Old French was also spoken in the Kingdom of Sicily, and in the Principality of Antioch and the Kingdom of Jerusalem in the Levant.
