Globally, Runjuan (รัญจวน 
, 润娟 
, Runjuan 
) is quite a rare dominantly female, but infrequently boy's first name. The first name Runjuan is characteristic of Thailand, where it is quite a rare largely female, but uncommonly boy's name, and China, where it is a rare principally female, but very seldom boy's name. Very seldom, Runjuan is the last name as well as the forename.
