Meaning & Origin
A nickname for someone who is the third person in the family sharing his father's name.
Trey is a boy's and girl's baby name of Middle English origin, from the Middle English and Old French treis meaning "three," traditionally given to a son who is the third generation to bear the family name. It carries a confident, sporty edge.
With over 40,000 U.S. births recorded, Trey has been a consistent presence since the mid-20th century. It works both as a standalone given name and as a nickname for names ending in "-trois" or "-tres," and has strong associations with basketball culture.
