Across the world, Kadu (Kadu 
, Каду 
) is a common primarily male, but very seldom feminine first name. The first name Kadu is characteristic of India, where it is quite a rare predominantly male, but scarcely feminine name, Ethiopia, where it is a rare unisex name, and Brazil, where it is a rare principally masculine, but very seldom feminine name. Not in comparison with a country's population, it is the most numerous in India, Brazil, and Indonesia. More prevalently, Kadu is the last name as well as the forename.
