Boy Cat Names That Start With J

  1. Jiraiya
    • Origin:

      Japanese
    • Meaning:

      "young thunder"
    • Description:

      The name Jiraiya was created in 1806 for yomi-hon — a type of book from the Edo Period — called Jiraiya Monogatari. The character was revived later in the century for a folk tale series Jiraiya Gōketsu Monogatari, in which Jiraiya, a ninja, shapeshifts into a giant toad.
  2. Janus
    • Origin:

      Latin
    • Meaning:

      "doorway"
    • Description:

      The meaning of this ancient Roman god's name relates to transitions, hence its connection to the name of the first month of the new year, a time of fresh beginnings. Janus is usually depicted as a two-faced god facing in opposite directions, since he looks both to the future and the past. It's no surprise then, that Janus is one of the premiere January baby names. The Slavic form Janusz is more commonly used than the English, represented by the Polish cinematographer Janusz Kaminski, who has shot all of Steven Spielberg's films from Schindler's List to Lincoln.
  3. Jazz
    • Origin:

      Word name
    • Description:

      Jazz as a full name is used slightly more often for boys than girls and has a distinctive, well, jazzy feel. Jazz is also occasionally used as a nickname for Jasper, much more often for Jasmine or Jazlyn. Could work as a middle name.
  4. Jacoby
    • Origin:

      Variation of Jacob, Hebrew
    • Meaning:

      "supplanter"
    • Description:

      Jacoby, a surname spin on Jacob shot up the charts in the middle of the 2000's, thanks largely to the popularity of Jacoby Ellsbury, the first Native American of Navajo descent in the Major Leagues, but has been dropping steadily since it peaked at Number 423 in 2008. As of 2022, it dropped out of the US Top 1000 and is given to around 170 boys each year.
  5. January
    • Origin:

      English word name
    • Meaning:

      "month name"
    • Description:

      Cooler than the older month names like April and May, and a highly unusual and eye-catching choice. The most famous real-life January is female – January Jones – but the month is named for the Roman god Janus, who presided over doors and new beginnings.
  6. Jordy
    • Origin:

      Diminutive of Jordan
    • Description:

      A cutesy short form of Jordan that's never been overly popular. Pro Bowl wide receiver Jordy Nelson is one famous bearer.
  7. Jovan
    • Origin:

      Slavic variation of John, or Latin
    • Meaning:

      "Jove-like, majestic"
    • Description:

      Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.
  8. Jove
    • Origin:

      Mythological name
    • Description:

      Another name for Jupiter, king of the Roman gods, this jovial name is eminently ready for modern use. Feminine variations include Jovita and Jovie.
  9. Journey
    • Origin:

      Word name
    • Description:

      Journey is one of the hot new spiritual names. Although Journey was given in 2015 to over 1100 baby girls and fewer than 100 baby boys, it's more visible on the celebrity baby scene as a boys' name: Megan Fox and Brian Austin Green just chose the name for their third son, who also has the unisex middle name River.
  10. Joao
    • Origin:

      Portuguese variation of John
    • Meaning:

      "God is gracious"
    • Description:

      A Portuguese classic, typically spelled with a tilde over the A. Many members of the Portuguese royal family were named João, and today it’s associated with a number of Portuguese and Brazilian footballers.

      Diminutive of Jeffrey, Jefferson
    • Meaning:

      "pledge of peace"

  12. Junior
    • Origin:

      Latin
    • Meaning:

      "young"
    • Description:

      The line should end with Junior Soprano. While most would expect this to be a nickname rather than an actual given name, Junior has always ranked in the US Top 1000, hitting its peak in 1925 at Number 116.
  13. Jaguar
    • Origin:

      Animal name
    • Description:

      Grrrr.
  14. Jeter
    • Origin:

      French or German surname
    • Description:

      Jeter, which of course is used as a first name only because of Yankee star Derek, rhymes with Peter and may be derived from the French surname Jette, which was often bestowed on foundlings because it means "thrown out," or the German Jetter, an occupational name meaning "weeder." If your husband insists on Jeter, counter with Percival.
  15. Jinx
    • Origin:

      English word name
    • Meaning:

      "attracting bad luck"
    • Description:

      Popular choice for black cats.
  16. Jojo
    • Jonael
      • Origin:

        Hispanic
      • Description:

        This is another example of a name propelled into usage by a celebrity. Prior to 2015, Jonael had only been given to more than 4 boys in a given year once; that year was 2004, when 6 boys in the US received the name. However, in 2015, Jonael Santiago won La Voz Kids, Telemundo's Spanish children's version of popular reality competition show The Voice. As a result, this name immediately entered the US Top 1000 at Number 919. We'll see if it continues to rise, or if this is just its fifteen minutes of fame.
    • Jersey
      • Origin:

        English place name
      • Meaning:

        "Geirr's island"
      • Description:

        The New Jersey cities of Camden and Trenton are in, but the name of the state has not caught on to anywhere near the same extent, possibly due to its association with knitted pullovers and reality TV. Nevertheless, Jersey peaked as a masculine name in 2022, when it was given to around 60 boys.
    • Jiminy
      • Jiddu
        • Description:
