Jack, one of the most popular boy's names of all-time, comes from the long line of names derived from John, which itself comes from the Hebrew name Yohanan, meaning "God is gracious." Jack was a top-50 boy's name in the United States every year between 1900 and 1951. It stayed in the top-200 until re-entering the top-50 in 2000, where it remains today. In fact, Jack has now been a top-15 boy's name since 2021 and will only grow more popular since singer Justin Bieber and Hailey Bieber named their son Jack Blues, born in 2024.
