Jax
Masculine · “Short form of Jackson”
Jax is overwhelmingly a boys’ name — 25,085 boys against 224 girls since 1880.
Jax is Jackson with everything trimmed away but the snap at the end — one syllable, one breath, the x doing the work of two letters. Behind it sits one of the oldest names in Europe: Jackson means "son of Jack," and Jack was the medieval English pet form of John. Very few names manage to sound this new while resting on a foundation that deep.

From Yochanan to Jax
The story of Jax
The surname Jackson is old and thoroughly English — a patronymic formed from Jack, which stood in for John for centuries in everyday speech. American parents began moving surnames to the front of the name in large numbers, and Jackson came along with the rest; from there the clipped Jax followed naturally, helped by a broader taste for x endings that also produced Jaxon and Jaxson. It reached the US charts only in the last few decades, making it one of the genuinely recent arrivals rather than a revival. The lead character of the FX drama Sons of Anarchy, which ran through the late 2000s and early 2010s, went by Jax, and the name's climb belongs to those same years.
Meaning
Short form of Jackson, "son of Jack"
Jack has been the English pet form of John since the Middle Ages, and John comes from Hebrew Yochanan, "God is gracious." So the meaning runs through two links before it lands, but the chain itself is not in doubt. The x spelling belongs to the same modern family as Jaxon and Jaxson.

The Kelvin test
Every popular name lives one long story — a climb, a peak, a slow settling back. Jax's later chapters haven't been written yet, so we borrowed them: Kelvin climbed just as high around 1965, and its whole arc is on record. Line the two peaks up, and Kelvin's path sketches the road Jax is walking now.

The trade-off
- One syllable and phonetically obvious — readable on sight by anyone, including people who have never met the name before.
- Already as short as it goes, so there is no nickname negotiation and no long form to defend.
- Pairs cleanly with Jackson or Jaxon on a birth certificate if you want a longer formal option in reserve.
- Also charts in Scotland, so it is not confined to one country's records.
- Rare enough as a spelling that a child is unlikely to share it in a classroom.
- Said aloud it is indistinguishable from Jacks or Jack's, so expect to spell it over the phone and to see it written with a ck by well-meaning people.
- The name has no record before the last few decades and its wave is very recent, which means it reads as a marker of one particular stretch of years rather than as ageless.
- The exact spelling is uncommon, but the sound is not: Jackson, Jaxon, Jaxson and Jaxton are all nearby, so a Jax may still hear his name called across a playground and turn to find it was someone else.
