Jestin as a Baby Name. Meaning and Origin of Jestin

What is the meaning of the name Jestin ?

The baby name Jestin is a Male name , 2 syllables long and is pronounced /ˈdʒɛstɪn/ (JES-tin).

Jestin is Latin, Welsh in Origin.

Jestin is a modern Anglicized and Welsh-influenced variant of Justin and the Welsh forms Jestyn and Iestyn, ultimately from Latin Iustinus, derived from iustus meaning “just, fair, righteous.” In Welsh, Iestyn served as the traditional cognate, and the e spelling in Jestin reflects anglicization while keeping the two-syllable feel. The core meaning across all forms remains “upright, just, righteous.”

Use has roots in medieval Christendom via saints named Justin, most famously the second-century philosopher-martyr, helping the name spread across Europe. In Wales, it evokes Iestyn ap Gwrgant (d. c. 1111), a noted ruler of Morgannwg. Today, Jestin is uncommon in English-speaking registers, seen as a distinctive alternative to Justin or as a Welsh-leaning choice. Related forms and variants include Justin, Justyn, Jestyn, Iestyn, and the feminine Justine and Justina; short forms may include Jes. The name carries a quietly virtuous tone without feeling old-fashioned.
