Across the world, Yongsook (Yongsook 
, ยงสุข 
) is a rare dominantly feminine, but infrequently boy's forename. The forename Yongsook is characteristic of South Korea, where it is a rare female name, and Thailand, where it is a very rare principally boy's, but very infrequently feminine name. Much less frequently, Yongsook is the last name as well as the forename.
