One-of-a-Kind Baby Names Stand Out

Updated Mon Mar 31 2025

Truly one-of-a-kind baby names are names that nobody is using – or at least nobody is using them in the US right now. So, if you're hoping to give your baby a name that is truly their own, then you've come to the right place.

Many one-of-a-kind names are simply undiscovered, whether that’s because they come from a little-known naming culture, or have long been lost to history. Alternatively they might be so new that no one has thought to use them yet.

We've cross-referenced the national baby name records with our extensive database of over 70,000 names to find Nameberry’s totally unique names. 300+ of our favorites are listed here – and some of them are very unusual – you have been warned!

Former Faves

While some names are perennially popular and some fall in and out of style, there are plenty of more that have had a brief moment in the spotlight, then disappeared completely from the charts. The names listed below have all appeared in the US or UK Top 1000s, but are currently out of use.

While some names might be better off left to history, others might fit the trend of “Croc names” – names so uncool that they might just start to feel cool again on a baby. We'll leave you be the judge!

Favorites Reimagined

It happens: you fall in love with a beautiful name, certain that you've found an undiscovered gem, except when you check its ranking on the charts, it's actually everyone else's favorite too. Plenty of parents can overlook the popularity for the name they love – and high charting choices are popular for a reason – but for some, it's a total deal-breaker.

"Too Popular" is highly subjective, but if your definition of “too common” is anything within the Top 7000, then this list is for you. We've found one-of-a-kind counterparts to some of the most popular and fast-rising names of 2023, so you can find the sweet spot between the popular name you love and the unique style you prefer.

If you love Piper, for example, you might also enjoy Fifer. If you love Luna and Elodie, how about Eluned? You could consider swapping Zachary for Thackeray or switching Theodore for Calidore or Leodore.

Below, we've got a list of more of these totally unique swaps, with their popular counter-parts listed in parentheses:

Sebby (Sonny, Teddy, or Eddie)

Wystan (Weston or Tristan)

Sylvander (Sullivan or Evander)

Cornelian (Cassian or Connor)

Rosen (Rhodes or Rowan)

Elioenai (Elias, Elijah, or Elio)

Rilian (Killian or Cillian)

Padgett (Truett or Patrick)

Azor (Azariah)

Majvi (Maisy, Ivy or Maya)

Endellion (Elowyn)

Miffy (Murphy)

Lovi (Jovie)

Cleome (Cleo or Chloe)

Maxeline (Adeline or Madeline)

Merrily (Millie)

International Stars

Many cool international names have migrated over to the US, but there are so many undiscovered options from the globe to explore.

For girls, we especially like the Dutch name Madelief. With the floral meaning of "daisy", it ranks in the Top 250 in the Netherlands, but isn't being used in the US. There's also the magical Umay, a Mongolian and Turkish name derived from that of a goddess associated with childbirth.

For boys, the Finnish Toivo is a playful and optimistic choice, no longer used in the US but currently in the Finnish Top 20. The Romanian Cosmin could work as a fresh take on Cosmo, while the rugged Irish name Donnacha might appeal to those who like Desmond or Donovan.

The following names have recently ranked on international popularity charts, but are not in current use in the US:

Mythological Names

Mythological names are as fashionable as ever, with multiple celebrities choosing Athena for their daughters and the once unexpected Atlas approaching the US Top 100 Names for Boys. These mythic names are joined in the charts by Persephone, Freya, Ares, Adonis, Titan, Artemis, and Maeve.

If you like the idea of a mythological name but want one that's more obscure, then this list of overlooked names from myth and legend is might inspire you. From Tanith to Atalanta, Kalevi to Arno — we're seriously surprised that some of these are still so rare!

Only found in Fiction

There are lots of fictional monikers have become huge hits in the real world, with parents drawing inspiration from their favorite books, films, and TV shows. when it comes to naming their babies. Shakespearean choices like Ophelia, Imogen, and Juliet are on trend in the UK, while popular shows and films have brought more attention to the likes of Maeve and Otis, Castiel and Kylo, and Arya and Arwen.

There are however a whole lot of names that are memorable within their fictional realms but haven’t made that transition to real world usage – which some might argue is for the best! Below is a selection of these rare fictional names that parents aren’t choosing for their babies.

Nicknames

So you want a name that’s short, sweet, and highly distinctive at the same time? Of course it's not too much to ask!

This group of ultra-rare diminutives contains international nicknames (Kuno, Helmi), vintage short forms (Deenie, Clem), and those with a modern sensibility (Riff and Cosy). Take a look and find what suits your style:

Place Names

Unique place names are in abundant supply — all you need to do is pick up an atlas to be flooded with inspiration. While it may be easy to get carried away, not every rare city or country name you come across will be worth adapting as a baby name:

Corsica? Yes, plenty of familiar and "name-y" sounding elements to it: Cora-meets-Francesca-meets-Erica.

Copenhagen? Maybe for a fictional character? With the nicknames Penny, Hayes, or Connie perhaps?

Cork? Probably best left on the map (or in the bottle).

To get you started, we've curated our favorite place-inspired options below:

Word Names

New word names are being invented on the daily and range from whimsical choices like Wish to rugged ones like Trekker. The limit is only your imagination! Or, rather, your dictionary — and the real-life usability of the word if you're naming an actual human child.

Nature Names

Names with nature-related meanings feel especially on-trend at the moment – we see you cottagecore namers). They allow you to give your baby a name with a cool connection to the natural world in a way that's far more subtle than using a word name.

These one-of-a-kind options hail from around the world and relate to everything from flora and fauna (Lirio and Hirshel), to the ocean and the air (Dwynwen and Boreas). Check them out below:

Want rarer still? These names have never, ever, had a spot on the American popularity charts, meaning they’ve been used for fewer than five babies each year since 1880. That’s as close as you’ll come to a guarantee that your child will never encounter another person with their name.

If that’s what you’re after, one of these truly one-of-a-kind names could be the perfect fit for a baby:
