Favreau is a French surname. It is a diminutive of Favre, itself a southern French variant of Fèvre. The root name, Fèvre, is an occupational name meaning "blacksmith" in Old French, derived from Latin faber. The suffix -eau is a common French diminutive ending, often indicating "little" or associating with a characteristic. Thus, Favreau likely referred to "little blacksmith" or "son of the blacksmith," a typical French surname evolution. The name shares roots with other French surnames like Fabre (Occitan), Lefebvre, and Lefèvre, all deriving from the Latin word for smith. Variants also exist in other languages, such as Italian Fabbri, Fabbro, and Favero, and Occitan Fabre and Faure.
