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

An English diminutive of Isabel or Elizabeth that works best with a longer form on the birth certificate.

Ibby

This unisex name ranks among the most popular girl names in Norway, though it has a number of different roots.
 
On one hand, it can be derived from the Danish ibenholt meaning "ebony", making it a color name. On the other, it can be a feminine form of Ib, a Danish short form of the Biblical Jacob. 
 
As a masculine name, it is usually considered a Frisian variation of Ivo, a nature name meaning "yew wood". This meaning could be applied generally, since it could still derive from the Germanic root iwa, meaning "yew".

Iben

A rare vintage compound name formed from Ida plus Isabel, historically found mostly in Spanish speaking communities.

Idabel

Diminutive of Ignatius or its female form Ignatia – or, if you're thinking outside the box, of Ingrid or even Indigo. British actor, presenter and comedian Noel Fielding named his second daughter Iggy in 2020.

Iggy

This Arabic name is used for both girls and boys. The high-minded meaning can also be translated as esteem or veneration.

Ikram

Old German variant of Elizabeth, newly appealing today.

Ilsabe

Inas is one of those simple but rare names that's worth a look, whether you're trying to bridge Arabic and English cultures or are looking for a meaningful, unusual choice. No baby girls were named Inas in the US last year. For English speakers, the second syllable rhymes with has or jazz.

Also an Arabic boy name, Inayat feels fashionable for a girl because of the similarity to rising girl name Inaya.

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.
