Unique, unusual, and uncommon girl names come in many varieties, from ancient to modern, traditional to invented. The best 2025 unique names for girls are those unusual and rare choices that have deep roots, are attractive, and can fit into contemporary life. 

By rare, unusual and unique girl names, we mean names that don't rank in the Top 100 or even Top 1000 in most countries, which makes these names uncommon no matter where you live. Still, some unique names are more appealing than others.

Unique names with nature ties seem to be especially primed to rise in popularity. Along with Bay and Bee, unique nature names for girls we may see taking off include Fleur, Garnet, Lilac, Marine, Petal, and Solstice. 

Unique girl names with celebrity ties also have a better-than-average chance of becoming, well, less unique. These include Blue, Banks, Eleven, Tilda, and Winslet. 

Of course, there are thousands upon thousands of unique names for baby girls. The unique names for girls listed here are ranked in order of their popularity on Nameberry, for the first 50, and below that the unique girl names are ordered A to Z.

Unique, Rare, and Unusual Girl Names

The Indre is a river in France. Spelled Indra, it's the name of a powerful deity worshipped by Hindus, Buddhists, and Jains — roughly the South Asian equivalent of the Greek Zeus or Norse Odin. But either Indra or Indre might make a simple, captivating, attractive name for a modern little girl. 

Indre

Indu is truly unusual, but shares sounds with more popular choices like Indie and Indigo. Other moon names to consider: Luna, Serena, Io.

Inoa is an evocative choice from the South Seas. 

Inoa

One of three Cherokee names with the same meaning, along with Inali and Enoli, both male names.

Inola

A fresh nature name — Bluet is a dainty, low-growing plant with small, light blue flowers — that feels like a mix of jazzy word-name Blue and trendy surname Truett.

Bluet

Popular with the Puritans, this name of the shrewd and beautiful wife of King David and mother of King Solomon could be a bit of a load for a modern girl to carry. 
 Bathsheba is the name of the central character in the Thomas Hardy novel Far from the Madding Crowd and there's a Harry Potter character named Bathsheba Babbling, Ancient Runes professor at Hogwarts.

With Isabel getting so popular, parents are searching for new varieties of the name, and Isabeau is one that makes a lovely French twist. 
 Isabeau of Bavaria was the wife of King Charles VI of France--and it was possibly a nickname for Elisabeth. It is also the name of an opera by Pietro Mascagni, a retelling of the medieval English legend of Lady Godiva, and in the 1985 film Ladyhawke, Michelle Pfeiffer plays the heroine, Lady Isabeau d'Arjou, who assumes the form of a hawk during the day.

For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade. 
 
Derived from Greek, Isadora is the feminine form of Isidore, comprised of the elements Isis, the Egyptian goddess of the sky and nature, and doron meaning "gift". Isidora is an alternative but equally well-established spelling, used by a fourth century saint.
 
Quirky couple singer Bjork and artist Matthew Barney were ahead of the trends when they named their daughter Isadora back in 2002, while fictional Isadoras include Isadora Wing, the liberated central character of Erica Jong's 1973 bestseller Fear of Flying, Isadora Quagmire in Lemony Snicket's A Series of Unfortunate Events, and the half-fairy-half-vampire titular character of Harriet Muncaster's series, Isadora Moon.
 
Given to around 150 girls in the US in a recent year, an Isadora could have the popular nickname Izzy, though Dora, Rory, Sadie, and Isa might be alternatives.

Isadora

As more parents look for unique alternatives to the popular Isabella — Isabeau and Isadora are two great examples — they may like the beautiful Gambian name Isatou. Isatou Ceesay is a Gambian activist who started a revolutionary recycling movement called "One Plastic Bag".

Isatou

An unusual botanical name, Astilbe could make an intriguing floral choice and work as an alternative to the likes of Aster, Thisbe, and Phoebe. It is the name of a hardy perennial plant with fluffy flowers that bloom in shades of pink, red, and white. 
 
Sometimes known as false goat's beard and false spirea, the flower gets its name form the Greek stilbe meaning "brilliance" and a meaning "without". Not the best of meanings and perhaps slightly confusing when you take a look at them in flower!
 
Astilbes are said to represent sensitivity and refinement and to promote spiritual growth and personal peace. 

These flowers are said to represent sensitivity, grace, and refinement. They are also known for their ability to encourage spiritual growth and promote inner peace.
