Around the globe, Иоан (Ioan 
, Yoan 
, Иоан 
) is a widespread predominantly masculine, but scarcely girly forename. The forename Иоан is characteristic of Greece, where it is a widespread masculine name, Romania, and Andorra, where it is quite a common boy's name (explore the name in all countries). Not in comparison with a country's population, the name is most common in Romania, Greece, and Indonesia. Very seldom, Иоан is the last name as well as the forename.
