Unique, Unusual, and Rare Girl Names

Unique, Unusual, and Rare Girl Names
Unique, unusual, and uncommon girl names come in many varieties, from ancient to modern, traditional to invented. The best 2021 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.

OttilieHeart

  • Origin:

    Feminine variation of German OTTO,
  • Meaning:

    "prosperous in battle"
  • Description:

    Ottilie and its diminutive Ottiline are a pair of names heard among the British upper crust, but have rarely been seen here since the 1880's. Though it has German roots via Otto, Ottilie has a distinctively delicate French feel.

FloraHeart

  • Origin:

    Latin
  • Meaning:

    "flower"
  • Description:

    Flora, the name of the Roman goddess of flowers and spring, who enjoyed eternal youth, is one of the gently old-fashioned girls' flower names we think is due for a comeback--alongside cousins Cora and Dora. Also the name of a saint, Flora has long been a favorite in Scotland where it was the name of the young heroine who helped Bonnie Prince Charlie make his way to France. Florence, Fiorella, Fleur, and Flower are translations, but we like Flora best of all.

CloverHeart

  • Origin:

    Flower name, from Old English
  • Meaning:

    "key"
  • Description:

    Clover is a charming, perky choice if you want to move beyond hothouse blooms like Rose and Lily, and it's recently become a new celeb favorite, chosen by both Neal McDonough and Natasha Gregson Wagner, who used it to honor her mother, Natalie Wood, one of whose most iconic films was Inside Daisy Clover.

IsoldeHeart

  • Origin:

    Welsh
  • Meaning:

    "ice ruler"
  • Description:

    Now that Tristan has been rediscovered, maybe it's time for his fabled lover in the Arthurian romances and Wagnerian opera, a beautiful Irish princess, to be brought back into the light as well.

ElowenHeart

  • Origin:

    Cornish
  • Meaning:

    "elm"
  • Description:

    A beautiful modern Cornish nature name that is rapidly picking up steam in the States: even spawning variant spellings like Elowyn and Elowynn. In its native region, it wasn't widely used as a name before the twentieth century, when the Cornish language was revived. A (currently) unique member of the fashionble El- family of names, it has a pleasant, evocative sound.

BirdieHeart

  • Origin:

    English
  • Meaning:

    "bird"
  • Description:

    Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.

CassiopeiaHeart

  • Origin:

    Greek mythology name
  • Description:

    Cassiopeia, the name of a mythological mother who became a stellar constellation, is challenging but intriguing, and has all those softening Cass nicknames available. With the rise of other otherworldly and mythical choices, from Apollo to Jupiter to Juno, Cassiopeia may just feel more possible for mortals now than ever before in its long history.

CaoimheHeart

  • Origin:

    Irish, Scottish
  • Meaning:

    "beautiful"
  • Description:

    Caoimhe, pronounced (more properly) kwee-va or kee-va, is a pretty and distinctive Gaelic name but one that could well lead to no end of confusion outside the Irish community. Even in its native habitat, it is sometimes spelled Keeva.

NellHeart

  • Origin:

    English, diminutive of Helen, Eleanor, et al
  • Meaning:

    "bright, shining one"
  • Description:

    Nell, once a nickname for Helen, Ellen, or Eleanor, is a sweet old-fashioned charmer that is fashionably used today in its own right. While Nell is perfectly in tune with contemporary vintage name style, it hasn't taken off the way some of its sisters have and so maintains an air of distinction. Use Nell or Nellie as a short for any name from Eleanor to Penelope or just name her Nell.

AstraHeart

  • Origin:

    Latin
  • Meaning:

    "of the stars"
  • Description:

    A kind of Jetsons-like, intergalactic name, it's attached both to a comic book character and to Princess Astra on "Doctor Who".

EilidhHeart

  • Origin:

    Gaelic
  • Meaning:

    "sun, radiant one"
  • Description:

    Long popular in Scotland, this attractive name is widely considered to be the Gaelic version of Helen. After the Normans introduced it into the British Isles, it was transformed into Aileen or Evelyn. It has rarely been heard in the US, but it is slowly starting to be used here too.

FleurHeart

  • Origin:

    French
  • Meaning:

    "flower"
  • Description:

    Fleur is a generic, delicate flower name that emigrated into the English-speaking world when John Galsworthy bestowed it on one of the Forsytes in his celebrated saga. More recently, there was Fleur Delacour, a French witch and the Beauxbatons champion for the Triwizard Tournament in Harry Potter.

CressidaHeart

  • Origin:

    Greek
  • Meaning:

    "gold"
  • Description:

    Cressida is a pretty mythological and Shakespearean heroine name much better known in Britain than it is here — an imbalance the adventurous baby namer might want to correct. For although the Trojan heroine of that name in the tale told by Boccaccio, then Chaucer, then Shakespeare, didn't have the greatest reputation — she was faithless to Troilus and broke his heart — the name today sounds fresh, crisp and creative.

SukiHeart

  • Origin:

    Japanese
  • Meaning:

    "loved one"
  • Description:

    One of the most familiar and usable Asian names.

CirceHeart

  • Origin:

    Greek
  • Meaning:

    "bird"
  • Description:

    In Greek myth, Circe, daughter of Helios, the sun, was a sorceress living on the island of Aeaea, who could turn men into animals with her magic wand, which is just what she did to Odysseus's crew in Homer's Odyssey, transforming them into swine. All was forgiven, however, as Circe and Odysseus later had a child together—Telegonus. The name and legend have appeared in countless forms, from a section of James Joyce's Ulysses to short stories by Julio Cortazar to Toni Morrison's Song of Solomon to films to DC comics to a dance by Martha Graham. So is Circe's seductive legend too powerful for a modern little girl to carry? Your call.

    Greek mythology name
  • Description:

FiaHeart

  • Origin:

    Irish or Portuguese or Italian
  • Meaning:

    "wild or weaver"
  • Description:

    Fia may be most notable at this moment as the Anglicized version of the Irish Fiadh, one of the fastest-rising names in the Republic of Ireland. The meaning of Fia or Fiadh is sometimes given as "deer" but that's in the sense of a wild deer, as the name relates to the ancient word for wild.

  • Origin:

    Irish, variation of Una
  • Meaning:

    "lamb"
  • Description:

ElspethHeart

    Scottish variation of Elizabeth
  • Meaning:

    "pledged to God"

    Elspeth is one of those names that never quite made it out of the British Isles--particularly Scotland, but possesses a winningly childlike charm. Elspeth was used by Sir Walter Scott for several of his female characters.

JezebelHeart

  • Origin:

    Hebrew
  • Meaning:

    "not exalted"
  • Description:

    Jezebel, the wife of King Ahab in the Hebrew Book of Kings, has long had a bad girl reputation. But in the modern secular world, this is somewhat mitigated by the feminist perspective of her as a strong woman, the power behind the throne. Previously avoided as a baby name, Jezebel is now, along with the also previously avoided Delilah and Desiree, coming into use, helped by its relation to other 'bel' name such as Isabel and Bella.

LilacHeart

  • Origin:

    English, from Persian
  • Meaning:

    "bluish or lilac"
  • Description:

    Could Lilac be the next Lila or Lily or Violet? It certainly has a lot going for it--those lilting double 'l's, the fabulous fragrance it exudes, and the fact that it's a color name as well, providing a ready made nursery theme. In addition, the lilac is symbolic of first love.

AntheaHeart

  • Origin:

    Greek
  • Meaning:

    "flowery"

CerysHeart

  • Origin:

    Welsh
  • Meaning:

    "love"
  • Description:

    Common name in Wales that's all but unknown in the U.S. Certainly an attractive choice ripe for export. In the UK it sits at Number 330.

IoHeart

  • Origin:

    Greek mythology name
  • Description:

    Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

BlueHeart

  • Origin:

    Color name
  • Description:

    Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy.

Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.

ClioHeart

  • Origin:

    Greek
  • Meaning:

    "glory"
  • Description:

    Clio is the name of the ancient Greek mythological muse of history and heroic poetry, one that is rich with modern charm and would make an intriguing choice, especially thanks to its dynamic o-ending. Unlike the sound-alike Cleo, which brings up visions of Cleopatra, Clio is very much a stand-alone name.

BlancheHeart

  • Origin:

    French
  • Meaning:

    "white"
  • Description:

    Blanche, which originated as a nickname for a pale blonde and then became associated with the notion of purity, was in style a century ago, ranking in the double digits until 1920. She then had to fight the stereotype of faded Southern belle, a la Blanche DuBois in Tennessee Williams's A Streetcar Named Desire and Blanche Devereaux in TV's Golden Girls. Now all three of the Golden Girls--Blanche, Rose and Dorothy--could be ready for revival, with Blanche sounding like a stronger, simpler alternative to Bianca.

BeeHeart

  • Origin:

    Animal name or diminutive of Beatrice
  • Meaning:

    "she who brings happiness"
  • Description:

    We've seen Beatrice and Beatrix climb in popularity, along with traditional nickname Bea. And now there's Bee, giving it a buzzy nature world spin, plus a tie to popular late night TV''s Samantha Bee, not to mention Aunt Bee on the old The Andy Griffith Show TV show. Bee can theoretically be short for any girl names starting with B.

TamsinHeart

  • Origin:

    English, contracted form of Thomasina
  • Meaning:

    "twin"

MaudeHeart

  • Origin:

    Variation of Matilda
  • Meaning:

    "battle-mighty"
  • Description:

    Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle.

    Maud's early popularity was influenced by the Tennyson poem that included the oft-quoted line, "Come into the garden, Maude." Then, in the 1970's, along came the sitcom Maude, featuring the vociferous and opinionated character Maude Finlay, putting a very different spin on the name. But enough decades have now passed for the name to have settled back into its soft, sweet pastel image.

It formed the basis of operas by Puccini and Massenet, and several films and TV series.

    Latin
  • Meaning:

    "heavenly"
  • Description:

    Celestine is a pretty, crystalline extension (actually a diminutive) of Celeste that would make a choice that is both delicate and strong. It is also a popular name in France.

EthelHeart

  • Origin:

    English
  • Meaning:

    "noble maiden"
  • Description:

    Occitan pet form of French Liliane
  • Meaning:

    "lily"
  • Description:

    Lilou is a charming, rarely heard import. Occitan is a language spoken in Provence, in the south of France, in which the suffix "ou" denotes a pet form — thus, Lilou as a short form of Liliane or its Occitan form Liliana or Liliano. Its popularity in France--where it's currently Number 12--can be traced to the 1997 film The Fifth Element.

ElectraHeart

  • Origin:

    Greek
  • Meaning:

    "shining, bright"
  • Description:

    Though the tragedies of the Greeks and Eugene O'Neill that used this name are filled with incest and murder, Electra is still a brilliant choice. Isabella Rossellini chose the gentler Italian verson, Elettra, for her now grown daughter.

EudoraHeart

  • Origin:

    Greek
  • Meaning:

    "generous gift"
  • Description:

    Eudora is the name of five minor goddesses of Greek mythology and a major goddess (in the person of Pulitzer Prize-winning Eudora Welty) of modern American literature. Eudora is pleasant and euphoneous and a possibility for rejuvenation.

FawnHeart

  • Origin:

    Nature name
  • Meaning:

    "a young deer"
  • Description:

    The doe-eyed Fawn is as gentle and soft as the baby deer it represents. And much like that baby deer, it carries with it the potential of new life. Fawn was featured at the bottom of the Top 1000 throughout the '60s and '70s — around the same time that Bambi came into play. But unlike Bambi, Fawn maintains relevance in the 21st century, thanks to its warmth and ties to the natural world. We would love to meet more baby girls named Fawn.

SigneHeart

  • Origin:

    Scandinavian
  • Meaning:

    "new victory"
  • Description:

    Signe could make an offbeat, more unusual alternative to Sydney or Sigrid. In Norse mythology, Signe was the twin sister of Sigmund. Can also be spelled Signy.

  • Origin:

    Scandinavian
  • Meaning:

    "beautiful"
  • Description:

It's related to Thor, and Tove and Tuva are the forms that survive and thrive in modern Scandinavia.

BronteHeart

  • Origin:

    Greek
  • Meaning:

    "thunder"
  • Description:

    This lovely surname of the three novel-writing sisters, now used as a baby name, makes a fitting tribute for lovers of Jane Eyre and Wuthering Heights. While the original name took an umlaut over the e, modern English speakers may find that more trouble than it's worth. Trivia note: The Anglo-Irish clergyman who was the father of Charlotte, Emily and Anne changed his name from the original Brunty. According to scholars, the family pronounced the name brun-tee, though in the 21st century world it's commonly pronounced bron-tay. In Australia, the name is more likely to take inspiration from Bronte Beach in Sydney. It was named after Lord Nelson, the 1st Duke of Bronté. He got his title from a town in Sicily, itself named after a mythological Cyclops.
