Luna: The Moon Name That Took Over the Baby Name Charts

Finding Luna on a Tuesday Night in November

My wife Sarah and I had been going in circles for weeks. We had a running notes app — names added, crossed off, debated over dinner, resurrected, abandoned again. Nothing was landing. Then one night in November, I stepped outside to take out the recycling — our rental in Northeast Portland, the one with the drafty back porch we keep promising ourselves we’ll fix — and I stopped dead in the driveway.

Full moon. Low and heavy over the Douglas firs, the kind of moon that makes you feel like you’re standing inside a painting. I stayed out there in the cold for longer than I had any reason to, and one word surfaced: Luna. I went back inside, said it out loud to Sarah, who was on the couch with her feet up and her laptop open to yet another name list, and she just looked at me. “That’s it,” she said. That was three weeks ago. We haven’t seriously considered another name since.

I know that probably sounds a little too tidy, a little too meant-to-be. But naming a baby is exactly the kind of thing where you’re willing to accept a little mythology. And if any name can carry that kind of origin story, it’s this one.

What Luna Actually Means

Luna comes straight from the Latin luna, meaning moon. But “moon” undersells it. In classical Latin, luna also referred to the divine light the moon cast — not just the celestial body, but its luminous effect on the world. The root connects to lux (light) and lucere (to shine), placing Luna in a family of words that includes “lucid,” “illuminate,” and “translucent.”

The moon in ancient thought was rarely just a rock in the sky. It governed tides, harvests, sleep, and the passage of time. Luna captured all of that — cyclical, radiant, dependable in its phases. The name carries that resonance forward. When you name a daughter Luna, you’re not just picking a pretty astronomical reference. You’re invoking something ancient that understood the moon as a source of order and illumination in a dark world.

Where the Name Comes From

Luna was the Roman goddess of the moon — one of the earliest and most significant deities in the Roman pantheon. She was typically depicted driving a silver chariot across the night sky, her crescent crown casting light over sleeping cities. The Greeks had their own moon goddess, Selene, but Luna was distinctly Roman: civic, elegant, associated with the rhythms of public and domestic life.

The name spread through Romance languages almost unchanged — luna in Spanish, Italian, and Portuguese means moon to this day. In French it softened to lune; in Romanian, lună. As Christianity reshaped European naming conventions through the medieval period, Luna largely fell out of fashion as a given name — the old goddess associations made it feel pagan. It survived in literature and poetry, where the moon has always been essential, but it rarely appeared in baptismal records before the twentieth century.

Its modern resurgence happened first in Spanish-speaking communities in the Americas, where luna remained a living word in daily speech and the name never fully disappeared. From there it crossed into mainstream English-language use with remarkable speed, arriving in American popular culture carrying both its Roman gravity and its Spanish warmth.

How Popular Is Luna Right Now

Luna sits at #13 for girls in the United States according to the Social Security Administration — a remarkable position for a name that was essentially invisible in American records just two decades ago.

The trajectory tells the real story. In the entire 1980s, roughly 115 girls were named Luna in the U.S. The 1990s brought that total to around 552 — still tiny. The 2000s saw 4,737 Lunas registered. The 2010s produced over 34,000. And the 2020s are already tracking past 40,000. That’s not a slow climb. That’s an explosion.

What drove it? A few things converged: the broader trend toward nature-inspired names, the growing influence of Spanish-heritage naming culture in the U.S., and — I’ll get to this — a fictional character who made the name feel both whimsical and brave. By the time celebrities started using it publicly, Luna was already becoming mainstream. Now it’s firmly in the top 15, which means your daughter will likely share her name with at least one classmate. That’s worth knowing going in. For me and Sarah, it doesn’t diminish the name at all — it’s popular because it’s genuinely good.

Famous Lunas Worth Knowing

Luna Lovegood is the character that sealed the deal for a generation of parents. Introduced in Harry Potter and the Order of the Phoenix, Luna is eccentric, fearless, and perceives things others dismiss or can’t see. Rowling named her deliberately — the lunar association hints at her otherworldly quality — and she became one of the series’ most beloved figures. For anyone who grew up with those books, the name carries her particular brand of quiet, unshakeable courage.

Luna, daughter of Chrissy Teigen and John Legend, was born in 2016, and the celebrity visibility almost certainly accelerated the name’s already-rising trajectory. Teigen spoke openly about wanting a name that felt both soft and strong. The cultural moment didn’t create the trend, but it confirmed it.

Luna Vachon was a professional wrestler in the 1990s known for a fierce, theatrical persona — proof, if you need it, that this name holds up under intensity and doesn’t require a delicate owner.

Luna (the singer), born Luna Lee, is a South Korean K-pop artist and member of f(x) who has built a substantial international following — a demonstration of how cleanly the name translates across languages and cultures.

Luna Rossa is the Italian sailing syndicate that competes for the America’s Cup, the name chosen to honor Italian heritage and the image of a red harvest moon over the water. A sleek, powerful association if that world means anything to your family.

Luna Rioumina is a contemporary French fashion designer building a reputation in sustainable couture — for parents who prefer their name references from the design world rather than the entertainment one.

Variants and Nicknames

The closest thematic variants are the language equivalents: Selene (Greek moon goddess), Cynthia (a classical epithet for the moon), and Diana (Roman goddess who shared lunar associations). If you love the celestial theme but want something less common right now, those names are worth serious consideration.

Within the Luna family specifically: Lunette is a French diminutive, delicate and vintage-feeling. Lunara and Lunaria appear in fantasy literature and occasionally in actual birth records — longer, more elaborate forms for parents who want something further from the mainstream. Luciana shares the Latin lux root and has a similar warmth, plus considerably more history as a given name in its own right.

For nicknames, Luna is already short — four letters, two syllables — which makes it naturally nickname-resistant. Most kids named Luna simply go by Luna. Some families use Lou or Lu as a casual shortening. Lulu appears occasionally, though that starts to feel like a distinct name rather than a nickname. Lune, the French form, surfaces as an affectionate shortening with a quietly Continental feel.

In Spanish-speaking households, the diminutive Lunita — little moon — functions as a term of endearment rather than a formal name. I could absolutely see myself using it in her early years, even though we’re not a Spanish-speaking family. Some words earn their passage.

Why I Keep Coming Back to This Name

I’ve made my peace with the fact that Luna is popular. What I keep returning to is what the name actually says. It doesn’t describe a quality we’re projecting onto her — bravery, grace, intelligence — the way many names do. It names something in the world that is beautiful and ancient and constant. The moon was there before we were, and it will be there long after. Naming a daughter after it feels less like a wish and more like an acknowledgment.

There’s also something right about how it sounds in our house. Sarah has a one-syllable last name, and we needed something that could carry real weight on its own. Luna does that. It lands. The L is soft, the a at the end opens up — it feels complete when you say it aloud, which I’ve been doing more than I’d like to admit, to the mild confusion of our dog. We haven’t told anyone the name yet. We’re waiting until she arrives. But in my head, when I imagine the specific person we’re about to meet, she’s already Luna.
