Isla: The Celtic Island Name That's Quietly Climbed to #35

The Name That Stopped Me Mid-Sentence

My wife Priya and I have been circling baby names for weeks now, filling a shared Notes app with contenders and shooting down each other’s suggestions with increasingly creative excuses. We’re expecting our daughter in late May, and living in Denver means we’ve had a lot of long winter evenings to sit by the fire and argue about whether a name sounds “too try-hard” or “too playground-ready.”

The name Isla came to me on a Wednesday night in January. I was deep in a re-read of an old travel journal from a trip Priya and I took years ago, before marriage and mortgages — a two-week loop through the Scottish Highlands that still feels like a fever dream of green hills and ferry crossings and pubs that smelled like woodsmoke. Somewhere in the middle pages I’d written it down: Isla of Mull. The island we’d taken a day trip to, grey-skied and dramatic and absolutely perfect. I’d written beneath it: This place feels like it was made for people who need to slow down.

I said the name out loud to the empty living room. Isla. EYE-lah. Two syllables, a soft landing, something ancient and airy about the whole shape of it. I texted Priya immediately, even though she was already asleep. Her reply the next morning was a single word: Yes. Sometimes a name just lands.

What Isla Actually Means

Isla carries two distinct meanings, and what makes the name extraordinary is how well they complement each other. The most immediate is geographic: island. In the Celtic linguistic tradition, the concept of island runs deep — bounded land surrounded by water, self-contained and shaped by its own edges. An island isn’t isolated so much as it’s defined. There’s a quiet integrity in that image, a sense of a thing that knows what it is.

The second meaning, devoted to God, traces through the name’s connection to Gaelic ecclesiastical tradition. Islands in Scotland and Ireland were frequently the sites of early Christian monasteries — places of devotion deliberately separated from the noise of the mainland. The Isle of Iona, just off the coast of Mull, is the most famous example: a small slab of rock that became one of the holiest sites in early Christianity. So when Isla carries devoted to God, it isn’t spiritual abstraction — it’s rooted in a specific geography of faith, in the image of monks crossing grey water to reach somewhere quiet enough to mean it.

Put the two meanings together and you get something richer than either alone: a person who stands apart, self-contained and strong, shaped by a particular kind of devotion. That’s not a bad thing to hope for in a daughter.

Where the Name Comes From

Isla is firmly Celtic in origin, with its deepest roots in Scottish Gaelic. The River Isla runs through Perthshire and Angus in eastern Scotland, and the given name almost certainly derives from this waterway — a common pattern in Celtic tradition where rivers, mountains, and landscapes become personal names across generations of use.

The name sat quietly in Scottish regional use for centuries before spreading southward into England and eventually crossing the Atlantic. It belongs to the same Celtic linguistic family as Aoife, Niamh, and Saoirse — names that look opaque on paper but carry unmistakable sound when spoken aloud. What sets Isla apart from its Celtic siblings is its spelling transparency. Unlike Niamh (NEEV) or Caoimhe (KEE-va), Isla is phonetically accessible to any English speaker who encounters it cold. That accessibility has almost certainly fueled its international spread.

There’s also a parallel thread in the Spanish-speaking world, where isla is simply the everyday word for island. A parent in Buenos Aires or Mexico City could choose the name with an entirely different cultural intention and arrive at the same spelling — though the pronunciation diverges. The Gaelic version is always EYE-lah. The Spanish EES-lah is a different name wearing the same letters, which is worth knowing if your family bridges both worlds.

How Popular Is Isla Right Now

Isla currently ranks #35 for girls in SSA data — a genuinely high position that puts it in the company of established favorites like Eleanor, Violet, and Nora. But the decade-by-decade picture tells a more complicated story, and I think it’s worth being honest about it.

In the 1980s, Isla ranked around #55 in the US charts. By the 1990s it had slipped to approximately #144. Then it largely disappeared: the 2000s saw it fall to around #1,925, and by the 2010s it had dropped to roughly #22,864. The name was essentially invisible in American nurseries for two solid decades.

What’s happened since is remarkable. The current rank of #35 represents a sudden, steep ascent — the kind of trajectory that suggests Isla isn’t just trending but actively establishing itself as a mainstream choice. [Link: popular girl names 2020s] My honest read on where it sits right now: this is a name in a genuine sweet spot. It’s familiar enough that teachers will recognize it and grandparents can pronounce it, but it hasn’t yet reached the saturation point where your daughter shares her name with three classmates. That balance is genuinely rare. If the current curve continues — and there’s little reason to think it won’t — Isla could push further into the top 20 within the next few years.

Famous Islas Worth Knowing

Isla Fisher — the Australian actress best known for Wedding Crashers and Now You See Me, whose high-profile career through the 2000s almost certainly introduced the name to a generation of American parents who’d never encountered it before.

Isla Blair — Scottish actress who appeared in the James Bond film The Living Daylights and an extensive run of BBC productions, representing an older generation of prominent name-bearers.

Isla St Clair — Scottish folk singer and television presenter who was a household name in the UK during the 1970s and ’80s, keeping the name visible in British culture across multiple decades.

Isla Cameron — a Scottish folk singer and actress from the 1950s and ’60s whose recordings of traditional Gaelic songs helped preserve a musical heritage directly tied to the landscapes the name comes from.

Isla Phillips — granddaughter of Queen Elizabeth II and daughter of Peter Phillips, making her part of the extended British royal family and a contemporary bearer of the name in a very public context.

The pool of famous Islas is still relatively modest compared to names with centuries of mainstream use — but the ones who carry it tend to be distinctive, often artistically grounded, and rooted in British or Celtic culture. That coherence feels right.

Variants and Nicknames

The name doesn’t have a sprawling family of formal variants, which is part of its appeal. A few are worth knowing:

Islay — the alternate spelling that reflects the actual Scottish island in Argyll, famous for its whisky distilleries. Pronounced identically to Isla in most English-speaking contexts, but the extra letter signals a more explicitly Scottish connection for families who want that specificity.

Isolde — a longer, more elaborate Celtic relative, famous from the Tristan and Isolde legend. It shares linguistic roots and a certain lyrical quality, though it’s a considerably heavier name to carry through daily life.

Ayla — not technically a variant, but frequently considered by parents drawn to Isla’s sound. Turkish in origin, meaning moonlight or halo, it offers the same two-syllable vowel-led rhythm with a different cultural anchor entirely.

As for nicknames, Isla naturally resists shortening — there isn’t much to trim without losing the whole name. Some families land on Izzy, which is warm and playful without skewing too young. A few parents use Issy with the double-s. Priya has already started calling her little island, which isn’t quite a nickname but feels exactly right.

Why This Name, in the End

There’s something I keep returning to when I sit with Isla as a name for our daughter: an island isn’t isolation — it’s integrity. A thing that holds its own shape, that knows where its edges are, that doesn’t dissolve into everything surrounding it. I want that for her. I want her to be someone who can stand in the middle of a loud world and still know exactly who she is.

And then there’s the fact that I wrote this name down in a journal on the Scottish coast years before I had any idea I’d one day have a daughter to give it to. It was just a beautiful place. It turns out it was also a beautiful name, waiting. Somehow, on a January night in Denver, it found its way home.
