What Does Jack Mean?

Looking for a strong, traditional name for your baby boy? Jack might be the perfect pick for you.

The name Jack is a derivative of John, which originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to, you guessed it, Jack. There is also a theory that Jack is Celtic in origin, meaning "healthy, strong, and full of vital energy."

Interestingly, the name was so common in the Middle Ages that Jack became a generic term for a man. Think about the phrase "jack of all trades"—a person who can do many different types of work.

Plus, the J name is frequently used in fairy tales and nursery rhymes, such as "Jack and the Beanstalk," "Jack and Jill," "Little Jack Horner," and "Jack Sprat."

  • Origin: English
  • Gender: Jack is traditionally the masculine form of the name and means "God is Gracious." However, both Jack and Jac are considered gender-neutral. Feminine variations, such as Jacklyn and Jacqueline are common.
  • Pronunciation: Jak

Although many baby names are separated by gender, Verywell Family believes that sex does not need to play a role in your name selection process. It’s important to select a name that you feel suits your new baby the best.
