In all the world, วิทูน (วิทูน 
) is a rare principally boy's, but scarcely feminine first name. The first name วิทูน is characteristic of South-eastern Asia, particularly Thailand, where it is a rare principally masculine, but very infrequently female name. Much less frequently, วิทูน is the last name as well as the forename.
