Meaning & Origin
A diminutive of the male given names Zachariah or Zachary.
Zack is a boy's baby name of Hebrew origin, a shortened form of Zachary or Zachariah, meaning 'God has remembered' or 'the Lord recalled.' It has worked as a standalone name since at least the mid-20th century, carried by actors, athletes, and musicians.
Zack has an easy, approachable energy — it's the name of the cool kid who's actually kind, the class president everyone actually likes. Short enough to stand alone, familiar enough to feel grounded. From Zack Morris to Zack Efron, it wears its casual confidence well.
