Boy Cat Names That Start With M

  1. Morris
    • Origin:

      English variation of Maurice
    • Meaning:

      "dark-skinned"
    • Description:

      Morris is as quiet and comfortable as a Morris chair, and has the same vintage feel. Once a Top 100 name in the early 1900s, Morris fell completely off the roster in 1995, probably due to lingering fallout from his identification with Morris the cat's ("the world's most finicky cat") 9 Lives cat food commercials.
  2. Marcello
    • Origin:

      Italian and Spanish
    • Meaning:

      "young warrior"
    • Description:

      Based on the ancient name Marcellus, drawn from Mars the god of war, Marcello -- it's pronounced mar-chell-o -- is one of the most lush and attractive Latin names.
  3. Moses
    • Origin:

      Egyptian
    • Meaning:

      "delivered from the water"
    • Description:

      Gwyneth Paltrow and Chris Martin's choice of this white-bearded Old Testament name helped bring it into the modern age, along with brethren Elijah, Isaiah and Isaac. User-friendly nicknames include Moe and Mose.
  4. Mercury
    • Origin:

      Latin
    • Meaning:

      "Roman messenger god"
    • Description:

      Adventurous parents are starting to look back to names of ancient gods like Mercury, Zeus, and Apollo. This one is also a planet and a metallic element, and has a friendly nickname, Merc. The Roman god Mercury, which derives from the Latin words for trade or wages, is the patron of tradesmen and travelers and the fastest-moving planet in the solar system. Mercury is the planet associated with the sign of Virgo, so this is one of the prime names for Virgo babies.
  5. Merle
    • Origin:

      French
    • Meaning:

      "blackbird"
    • Description:

      Originally a nickname for someone who loved to sing or whistle, Merle is sleek but gentle, with a hint of great grandpa about it..
  6. Mario
    • Origin:

      Italian variation of Marius, form of mythological name Mars
    • Meaning:

      "warlike"
    • Description:

      Many may associate Mario with the popular platform game - unsurprising when it's the 5th best-selling video game worldwide, and was voted the 2nd best game ever by IGN in 2024. The titular plumber was apparently named after American businessman, Mario Segale, who rented a warehouse to Nintendo, and this in itself reflects that Mario is much more established than just a name for a video game character.
  7. Monroe
    • Origin:

      Scottish
    • Meaning:

      "mouth of the Roe river"
    • Description:

      Monroe is a presidential surname which feels fresher than Jackson, Lincoln and Taylor. Marilyn Monroe is a famous female namesake, but her smart Scottish surname feels equally usable for either sex. Plus, we think old man nickname Moe would sound both cool and adorable on a baby boy today!
  8. Monte
    • Origin:

      Diminutive of Montgomery, Norman, Spanish
    • Meaning:

      "man power; mountain"
    • Description:

      Monte, pronounced with two syllables as brother Monty, is an old-fashioned nickname-name that's reclaiming a certain amount of dash and charm. It was recently chosen by actor Guy Pearce--which may signal a comeback.
  9. Melchior
    • Origin:

      Dutch from Hebrew
    • Meaning:

      "city of the king; king of light"
    • Description:

      The least used of the Three Wise Men's names, but a strong option for bold namers to consider.
  10. Morpheus
    • Origin:

      Greek mythology name, god of sleep and dreams
    • Description:

      Though you may pray to the god of sleep for your baby to slumber through the night, a drowsy image is not the greatest one to inflict on your little boy.

      Spanish variation of Matthew
    • Meaning:

      "gift of God"
    • Description:

  12. Moritz

      German form of Maurice
    • Meaning:

      "dark-skinned"
    • Description:

      The unusual-to-the-English-ear Moritz is a Top 25 name in Austria and a form of Maurice or Morris, which are modern variations of the ancient Roman Maurus. There were several early saints named Maurus and a famous 3rd century Saint Maurice, who was a Roman infantryman who was martyred when he refused to worship Roman gods. The Moritz form also references the posh Swiss ski resort St. Moritz and Justine Moritz is a character from Mary Shelley's novel, Frankenstein.
  13. Mickey

    • Description:

      Pugnacious and spunky like the young Mickey Rooney and the original Mickey Mouse, but virtually never given to babies today.

      German
    • Meaning:

      "hardy, brave, strong"

  15. Moe
    • Origin:

      English, diminutive of Moses
    • Meaning:

      "delivered"
    • Description:

      If Gus and Max have made it, why not Moe? Can it be the lingering Three Stooges effect? We think that Moe, like Joe, is one of the friendliest and most open of regular guy nickname names and should get a little more attention.
  16. Montana
    • Origin:

      Spanish place-name; "mountainous"
    • Meaning:

      "mountainous"
    • Description:

      Relaxed western place-name that still has some masculine punch, but be warned: this whole posse of similarly trendy names, like Sierra and Dakota, will soon ride toward the sunset.
  17. Messiah
    • Origin:

      Aramaic word name
    • Meaning:

      "expected savior or deliverer"
    • Description:

      A handful of years ago, a judge in Tennessee ruled that parents could not name their son Messiah, "because there's only one." That decision has since been overturned and the name no longer looks out of place besides the growing number of Saints and Chosens.

      "iron man"
    • Description:

  19. Midnight
    • Origin:

      English, word name
    • Description:

      Nicole Richie and Joel Madden added this rocking name to the lexicon of day names, which have their roots in the African tradition of naming a child after the day of the week, time of day, or season in which he or she was born. But they wisely used it as a middle name.
  20. Major
    • Origin:

      Latin
    • Meaning:

      "greater; or, a military rank"
    • Description:

      This bold choice soared in popularity from 2008 to 2013, and now seems to have plateaued. But watch out—the character Major Major Major Major in the classic absurdist novel Catch-22 had a terrible time.
