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 our website, for the first 50, and below that the unique girl names are ordered A to Z.
