Across the world, ลูซี่ (Lusi 
, Lusie 
, ลูซี่) is a common predominantly girly, but very infrequently masculine first name. The given name ลูซี่ is habitual in Indonesia, where it is quite a common primarily girly, but very infrequently boy's name, Albania, where it is quite a rare epicene name, and the Dominican Republic, where it is quite a rare principally female, but very infrequently male name. Not in comparison with a country's population, it is commonest in Indonesia, India, and Tanzania. Much less frequently, ลูซี่ is the last name as well as the forename.
