, Uthailuk , Uthailak ) is a very rare dominantly feminine, but infrequently male forename. The given name อุทัยลักษณ์ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare principally feminine, but scarcely masculine name. Very seldom, อุทัยลักษณ์ is the last name as well as the forename.
