Isla is one of those names that sounds like it has always been around. It's soft, simple, a little wistful. It feels timeless. So most people are genuinely surprised to learn that, as a girls' name, Isla is almost brand new. A hundred years ago, virtually nobody was called it. Today it's one of the most popular names in Britain. That's a remarkable rise, and the story behind it is lovelier than you might expect.
Let's start with the question everyone asks first.
The name Isla is pronounced EYE-la. The "s" is completely silent. It rhymes with "island" and "Twila," not with "Bisla" or "Misla." This trips a lot of people up the first time they see it written down, and it's worth knowing if you're considering the name, because your daughter will spend a fair amount of her life gently correcting people. The good news is that once someone hears it said aloud, they almost never forget it. It's a quietly memorable name.
So what does Isla mean? The simplest answer is that it means "island." But there are actually two different threads tangled together here, and it's worth pulling them apart.
The first thread is Spanish. In Spanish, the word isla literally means "island," and it descends from the Latin word insula, the same root that gives us English words like "insular" and "peninsula." For Spanish speakers, the name simply is the word for island, which gives it a warm, sunlit, coastal feeling.
But the second thread, the Scottish one, is the real story of the name, and it's the reason Isla became popular in Britain.
Isla comes from Islay, a real island off the west coast of Scotland. Islay is pronounced exactly the same way as Isla, EYE-la, which is the whole point. It's the fifth-largest of Scotland's islands, sitting in the Inner Hebrides, and it's so beautiful that it has earned the poetic nickname "the Queen of the Hebrides." If you've ever enjoyed a smoky single malt whisky, there's a decent chance it came from Islay. The island is world-famous for its peaty, distinctive whiskies, and that quiet fame is part of the name's appeal: Islay is a place that British people know, love, and associate with something special.
So when parents name a daughter Isla, they are, knowingly or not, naming her after a windswept, green, gorgeous Scottish island. It's a place-name, in the same family as names like Brooklyn, Florence, or India. There's something grounding about that. The name has a real location behind it, somewhere you could actually stand.
Here's an honest detail that a lot of baby-name websites skip over: nobody is entirely sure what the name of the island itself originally meant. The root word is genuinely ancient and its meaning has been lost. Some scholars have suggested it may come from an old Celtic word, others think it could be pre-Celtic, perhaps even Norse. There's an old tradition that the island was named after a Pictish princess called Ile who lived around 1,300 years ago, though there's no firm evidence for her. The truthful answer is that the original meaning is unknown. When sources confidently tell you Isla means "swelling island" or "rocky place," they're repeating one theory among several. The honest version is gentler: Isla means "island" through the Spanish word, and it carries the name of Islay, whose own ancient meaning time has quietly erased.
For most of its history, oddly, Isla wasn't even a girls' name. The older form, spelled Islay or Ilay, was used as a rare masculine name in Scotland, carried by a handful of Scottish noblemen. It was only relatively recently that Isla settled firmly into use as a feminine name, and that the spelling shifted to the softer, simpler "Isla" we know today.
And then, in the 2000s, the name took off.
For most of the 20th century, Isla was a quiet Scottish regional name, rarely heard outside Scotland. Then something shifted. Part of the credit usually goes to the Australian actress Isla Fisher, born in 1976 to Scottish parents, who became internationally famous in films like Wedding Crashers and Confessions of a Shopaholic. She introduced the name, and its correct pronunciation, to millions of people who had never encountered it before. The wider early-2000s fashion for soft, vintage, gentle girls' names ending in that "-la" sound helped too.
Whatever the precise mix of reasons, the result was dramatic. According to the Office for National Statistics, Isla climbed into the top three girls' names in England and Wales and held that position for several years running. In 2024 it was the fourth most popular girls' name in the country, narrowly behind Lily. In Scotland, fittingly, it has been even more beloved, regularly ranking as one of the very top names. For a name that was almost unheard of in 1990, reaching the top five nationally is an extraordinary journey.
The name has a gentle royal connection too. Isla Phillips, born in 2012, is a granddaughter of Princess Anne and a great-granddaughter of the late Queen Elizabeth II. She holds no royal title, in keeping with her family's preferences, but her name added a quiet touch of royal approval at exactly the moment Isla was surging in popularity.
If you're wondering about nicknames, Isla is already so short and neat that it barely needs one. That's part of its charm. It's a complete, two-syllable name that requires no shortening. That said, families do find affectionate forms naturally: Izzy, Lala, or simply "La" for very small children. There are also a few alternative spellings around, including Islay, Isley, and Eyla, though the clean, simple "Isla" is by far the most common and the easiest for your daughter to live with.
As for personality and feel, Isla carries a particular kind of quiet strength. It isn't loud or showy. It doesn't try too hard. It suggests calm, nature, open landscapes, and a certain self-contained independence, the qualities of an island itself. It pairs beautifully with almost any surname, works on a baby and an adult equally well, and has the rare quality of feeling both modern and timeless at once.
So, is Isla a good choice? Like every name, that's ultimately for you to decide. But here is what's true about it. It's beautiful to say. It's easy to spell, once people learn the silent "s." It carries the name of one of Scotland's loveliest islands. It means "island" in the warm Spanish sense. It's popular enough to feel familiar and accepted, but it has only been widely used for a couple of decades, so it doesn't feel worn out. And it suits a person at every stage of life.
A small Scottish island, a soft silent letter, and a name that has quietly sailed from the Hebrides into homes all over the world.
For a name that means "island," Isla has travelled rather far.
