Baio is Portuguese, Spanish in Origin.

Baio is a Romance name with roots in Latin badius, meaning “bay-colored” or “dun,” especially of a horse. In Italian and Portuguese, baio names the reddish-brown “bay” coat. As a byname describing coloring, horsemanship, or a trade in horses, it evolved into a surname in medieval Italy, Portugal, and Galicia (where Baio is also a place name). As a given name, it is rare and modern, typically borrowed from the surname and used for all genders.

Records show de Baio, del Baio, and do Baio in late medieval sources. Variant and cognate forms include Spanish Bayo and Galician‑Portuguese Baio; related French is bai (adjectival). Italian surnames sometimes expand it to Baione or Delbaio. The core sense is “bay/chestnut-colored,” suggesting warmth and earthiness, and for some families it also marks ties to horses or to the Galician parish of Baio.
