Irish Names that Start With F

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity.

A hugely popular choice for boys in England and Wales, Finley has been used for both sexes in the US since the early 2000s, and has since become one of the most popular unisex names. Until recently, it was tilting slightly towards the girl side, however, as of 2024, it leans more masculine.

Flynn, a charming Irish surname, is still used only quietly, despite its easygoing, casual cowboy charm, unlike Finn which is a star of this genre.

Fiadh is the fastest-rising girls name in Ireland, derived from the ancient root word for "wild". Sassy but gentle at the same time, it also entered the England and Wales Top 1000 in 2020 and has been steadily rising ever since.

Fia may be most notable at this moment as the Anglicized version of the Irish Fiadh, one of the fastest-rising names in the Republic of Ireland. The meaning of Fia or Fiadh is sometimes given as "deer" but that's in the sense of a wild deer, as the name relates to the ancient word for wild.

It returned to the US Top 1000 in 2019 and has been rising since then, as a new generation of parents fall in love with the sound. It is especially popular in the Southern states.

Ferelith is an unusual yet deeply-rooted Scottish girl's name, also found in ancient Ireland and drawn from the Gaelic Forbhlaith or Forbflaith. While it went through a period of dormancy after the Middle Ages, there are some modern women named Ferelith, including actress Ferelith Young and Princess of Denmark Anne Ferelith Fenella Bowes-Lyon.

This was Irish name was once used exclusively for boys, and remains so in England and Wales where it's a Top 50 choice. In the US, however, celebs Jason Sehorn, Angie Harmon, and Lisa Marie Presley inspired many parents to consider this name for girls instead, after they chose it for their daughters. In fact, up until 2024, it ranked considerably higher for girls than it did for boys.

Finlay is a Scottish royal name: it belonged to Macbeth's father, Finlay MacRory--or Findlaech mac Ruaidri--that has a bit of a split personality. It has two acceptable spellings--Finlay and Finley, the first more popular in its native Scotland, where it ranks in the Top 10, the second in the US. It is also becoming more and more unisex in the States, with the Finley spelling now split between girls and boys, while Finlay was used last year for TEN TIMES as many boys as girls, about 50 to only five.

It’s been more than three decades since Ferris Bueller took his famous day off in the cult classic 1986 teen comedy movie, but we think the time for this name could and should be now! Especially with the recent rise of the hero's girlfriend, Sloane, up the baby name rankings. Half preppy, half rugged, it boasts that stylish S ending and has a cozy, retro feel.

Fallon was one of the first of the unisex surname names, but thanks to "Dynasty" in the 1980s it now has a feminine image. For a boy, try Phelan instead.

Fionn, the modern Irish form of Finn, is more popular in Ireland these days than Finn, which is rising fast in the U.S. where Fionn is virtually unknown. That's probably a good thing, because few Americans would know that Fionn and Finn have the same root and are pronounced the same, like the fin of a fish. It's the namesake of a great hero from Irish mythology, Fionn MacCumhaill, who acquired divine wisdom by eating an enchanted salmon of knowledge.

Fintan is an ancient Irish saints' name that in legend is also the name of the only person to survive The Flood. Popular in modern Ireland, Fintan is ripe for export to the US where it is rarely used but could make an excellent long form for the stylish Finn.

Fianna, a virtually unknown Irish name in the US, combines the best elements of Fiona and Brianna. In Irish and Scottish mythology, the Fianna were independent bands of warriors. It has ranked in Northern Ireland's Top 100 for girls several times over the past decade. The name also has potential political connotations: Fianna Fáil is a conservative Irish republican political party.

Finnigan is another way to spell Finnegan, one of the energetic Irish surname-names in vogue now. One note: While Finnigan, Finnian, Finley and so on are appealing names on their own, you don't need to use a longer form to get to Finn, which is a perfectly proper name all on its own.
