Irish Girl Names

Irish girl names are on very different popularity tracks in the US and in Ireland itself. The top Irish name for girls in the US is the surname-name Riley, a departure from the days when Kathleen and Bridget reigned as the most popular Irish names for girls.

Along with Riley, other Irish girl names in the US Top 1000 include Nora, Kennedy, Quinn, Reagan, Rowan, Finley, Cassidy, Sloane, and Teagan.

The classic Irish girls' name Nora is also a top name in countries as disparate as Sweden and Norway, Germany and the Netherlands, and Spain. Unique Irish girl names newly on parents' radar include Fia, Tierney, and Una.

Baby girl names popular in Ireland include Saoirse — popularized around the world by Oscar-nominated actress Saoirse Ronan — Fiadh, Aoife, and Caoimhe. Irish names for girls such as Molly and Erin continue to rank in both the US and Ireland.

Traditional Irish girl names such as Kathleen and Bridget are still used in the US, Ireland, and other English-speaking countries, but they no longer make the list of most popular Irish choices.

NoraHeart

  • Origin:

    Irish, diminutive of Honora, or Greek
  • Meaning:

    "light"
  • Description:

    Nora has two separate origin stories, as a derivative of both Honora and Eleanor. The Irish and Anglo-Norman version derives from Honora, based on the Latin word honor. The Hungarians spawned Nora as a short form of Eleonora, a variation of Eleanor.

RileyHeart

  • Origin:

    English, Irish
  • Meaning:

    "rye clearing; courageous"

    Riley originated as both an English and an Irish surname. The former was derived from British place names that got their names from the Old English words for “rye clearing.” Irish Riley is a variation of Reilly, a surname taken from the given name Raghailleach.

KennedyHeart

  • Origin:

    Irish
  • Meaning:

    "misshapen head"
  • Description:

    This attractive surname name still projects that Kennedy family charisma. While it didn't come into widespread use until long after the deaths of martyred heroes President John F. or Senator Robert Kennedy, Kennedy is now one of the most popular unisex names for girls as well as the top girls' name starting with K. This is one name that manages to sound trendy and classic at the same time.

QuinnHeart

  • Origin:

    Irish
  • Meaning:

    "descendent of Conn"
  • Description:

    Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning “descendent of Conn.” Conn has two possible derivations—the Old Irish cond, meaning “intellect,” or cenn, meaning “chief.” One of the most notable Quinn clans was from County Tyrone in Northern Ireland.

    "little king"

    A strong, straightforward Irish unisex surname, with a merry glint in its eye, Reagan has been leaping up the popularity lists, to become one of the top girl names starting with R. Some will inevitably link it to President Ronald, but spell it Regan and it's a Shakespearean name: a daughter of King Lear.

    Feminine variation of Brian
  • Meaning:

    "strong, virtuous and honorable"
  • Description:

    Many different versions of Brianna are in the Top 1000 -- a sure sign that, though pretty, Brianna's gotten more and more difficult to make distinctive. This is the most popular spelling. It entered the US list in 1976, rose to the Top 100 in 1988, then got as high as Number 14 in 1999. Country singer Trace Adkins called his daughter Brianna. Though it sounds like it might be a modern invention, the name actually appeared as far back as the sixteenth century in Edmund Spenser's poem The Faerie Queen.

    Irish or Welsh
  • Meaning:

    "little poet or fair"

  • Origin:

    Feminine variation of Brian
  • Meaning:

    "strong, virtuous, honorable"
  • Description:

    Spelled this way, Briana was coined by Edmund Spenser for his great literary work, The Faerie Queene, which gives the now-overexposed name a far classier pedigree than it's usually credited with. But spelling variations Breana, Breanna and onward are popular too, though feel more invented -- probably because they are. One enduring appeal of Briana and sisters is that they're girl names that mean strong, brave, or powerful, which may be why George R. R. Martin names his warrior maiden Brienne of Tarth.

  • Meaning:

    "bright, shining light"

    Irish Aileen and Scottish Eileen may be pronounced the same way or Aileen can be pronounced with a long a at the beginning.
