Also spelled Ines, this name of the prudish mother of Don Juan in the Byron poem has a touch of mystery, but has also been fully integrated into the American name pool.

Indie is an independent-sounding nickname name that is in the Top 100 in Wales. As a diminutive, it's growing in popularity -- along with indie films, indie publishing -- and the reason some parents are choosing names like India and Indigo. The Indie version seems more feminine, while Indy as in Indiana Jones tends toward the boyish.

Inara is an appealing choice with multiple origins, currently in the Top 500 in the UK and the Netherlands. Gentle looking but bright in feel, it is also on the rise in the US, possibly owing to its use in Joss Whedon's hit sci-fi series Firefly, featuring main character, Inara Serra.

A simple name that's rising fast in the US, likely inspired by the popularity of Isla and Ayla. This streamlined form might appeal to those who like Ana, Ivy, and Ada, and it brings a multicultural element to the name.

Indie — as in indie films — is the more girlish version of the name, but earthy, gender-neutral Indy is catching up slowly and steadily. Indy entered the Top 1000 for girls for the first time in 2023 after rising over 100 places. For a longer full name, vibrant Indigo remains more and more stylish each year.

Irina is a Russian ballet-inflected classic, one of the Three Sisters in the Chekhov play. While some Americans will pronounce this like Irene with three syllables, the pronunciation used throughout Europe, where it's widely used, starts with a short i as in it or if and a strong emphasis on the second syllable.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.

This name, stemming from the Mayan mythological figure of the Rainbow Lady, is a surprising pop hit, primarily among Hispanic parents.

A true maverick of a girls' name — even more so with this spelling, the least common between Indie, Indy, and Indi.

Truly multi-cultural, Ira can be: a Russian short form of Irina, meaning "peace"; a gender-switch of the Hebrew male name Ira, meaning "watchful"; a modern Greek and Finnish form of Hera, meaning "hero" or "protectress"; a Sanskrit name meaning "earth" or "enjoyment"; and a Basque nature name meaning "fern", from the word iratzea.

A name used in the Caribbean, taken from the Rastafarian term that translates best to "positive and powerful." Rastas often greet each other by saying, "Are you feeling Irie today?"

A warm, sunny, and extremely rare name, even within its native France. Idalie would be especially perfect to honor an Ida.

Isis has gone from magical, feminist name on the rise to the forbidden list because of the extremist terror group called ISIS, an acronym for Islamic State of Iraq and Syria. Unsurprisingly, Isis was one of the fastest-falling names in 2014, dropping 130 ranks to reach #706. Interestingly, however, since 2020, it has begun to see increased use again, and 2023 saw it given to 151 girls.

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.

Another strong Arabic name, related to Iman. Imani one is popular throughout the Muslim world but especially East Africa. It was chosen for her daughter by actress Jasmine Guy.

Ivory was last popular a hundred years ago. In 2013, it finally began to regain some momentum in the female rankings, reentering the Top 1000, while 2024 saw it jump up the charts again by over 100 places, making it a To 500 name.

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.

The calming variety of marijuana, used as a baby name every year since 1992.

Issa might make more sense if you're using it as a nickname for any one of the various names ending in -issa, but this spelling is also an Arabic and Hebrew boy name. The Isa spelling is almost exclusively feminine.
