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:
