Throughout the world, โสพจน์ (โสพจน์ 
, Sopoj ) is a very rare mostly male, but uncommonly female forename. The first name โสพจน์ is habitual in South-eastern Asia, particularly Thailand, where it is a very rare dominantly boy's, but infrequently girly name. Much less frequently, โสพจน์ is the last name as well as the forename.
