All over the world, دیاکو (Diyako 
, دیاکو , Deyok 
) is a rare principally masculine, but scarcely female forename. The first name دیاکو is habitual in Iraq, where it is a rare boy's name, and Iran, where it is a very rare masculine name. Much less frequently, دیاکو is the last name as well as the forename.
