Throughout the world, Байо (Bayo , Bajo , Байо , and others...) is a common mostly boy's, but seldom feminine first name. The given name Байо is characteristic of Sub-Saharan Africa, particularly Nigeria, where it is quite a common primarily boy's, but very infrequently feminine name, Gambia, where it is quite a common unisex name, and Ethiopia, where it is quite a rare gender-neutral name. Not in comparison with a country's population, it most frequently occurs in Nigeria, India, and Ethiopia. Also, Байо is the last name as well as the forename.
Байо is also a name for the fictitious and mythical characters: Baio .
