X Factor Baby Names

X Factor Baby Names

The letter X seems to all by itself create cool baby names. Think about Jackson, an already-trendy name made livelier by the Jaxon variation. Even classic names with an X, such as Alexander, seem more, well, exciting compared to other traditional names.

Along with Alexander and Jaxon, other baby names with an X in the US Top 200 include Axel, Xavier, Braxton, Ximena, Alexandra, Max, Maddox, and Xander. Even a silent X makes baby names infinitely cooler, such as in Croix, Deveraux, Margaux, and Roux. One X name you won’t see on this list: Alexa. Alexa is now inextricably linked to Amazon’s virtual assistant and as such, is one of the fastest-falling names of the moment.

However, there are plenty more wonderful names with Xs. Some of the best baby names with the X factor are here, ordered by their current popularity on Nameberry.

      In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, giving this name a dark yet mystical feel.

      Arizona place-name and Greek

      "dark red"
    • Description:

      Effortlessly cool with a hint of the mystical, Phoenix rolls a lot of trends into one: it's a place-name and a bird name, it ends in the stylish letter x, it's got in-built nicknames, and it's unisex too. Familiar but not over-popular, Phoenix ranks in the US and UK Top 1000s.

      Latin
    • Meaning:

      "light"
    • Description:

      Word name
    • Meaning:

      "gem stone; claw, nail"

      Unlike Pearl and Ruby and more like Jasper, this gem name works well as a boys name. With its strong final X, it feels similar to Alex, Phoenix, Jax, and Rex, while the shiny black quality of the stone feels reminiscent of Orion.

  18. Maximilian
    • Origin:

      Latin
    • Meaning:

      "greatest"
    • Description:

      This name once seemed a bit grand and pompous for an American baby boy, but a significant number of parents are now preferring it as a substantial platform for the nickname Max, among them Jennifer Lopez and Marc Anthony, who chose it for their twin son.
  19. Rex
    • Origin:

      Latin
    • Meaning:

      "king"
    • Description:

      Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.
  20. Braxton
    • Origin:

      English
    • Meaning:

      "Brock's settlement"
    • Description:

      Braxton entered the popularity ranks in 1985 and has been climbing steadily ever since. It has gained from the all-powerful X-factor, and perhaps also from the reality TV show, Braxton Family Values, featuring singer Toni and her sisters Traci, Towanda, Trina and Tamar. Though it might sound new, there was a prominent Confederate Civil War general named Braxton Bragg.
