Across the world, Christyan (Christyan 
) is quite a rare predominantly boy's, but very seldom girly first name. The first name Christyan is habitual in Brazil, where it is a rare male name, Mexico, where it is a rare dominantly male, but infrequently feminine name, and Afghanistan, where it is a rare masculine name. Not in comparison with a country's population, this name is the most popular in Brazil, Indonesia, and Mexico. Much less frequently, Christyan is the last name as well as the forename.
