Throughout the world, Isaie (Isaie 
, Isaïe 
) is quite a rare masculine first name. The first name Isaie is characteristic of Sub-Saharan Africa, particularly Cameroon, where it is quite a rare boy's name, Ivory Coast, where it is a rare boy's name, and Senegal. Not in comparison with a country's population, it is commonest in Sub-Saharan Africa, particularly Cameroon, Ethiopia, and Ivory Coast. Very seldom, Isaie is the last name as well as the forename.
