Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.
 Alexander is derived from the Greek name Aléxandros, composed of the elements aléxein, meaning "to defend," and aner, meaning "man." 
 
According to Greek legend, the first Alexander was Paris, who was given the nickname Alexander by the shepherds whose flocks he defended against robbers. He was followed by Alexander the Great, aka Alexander III, who conquered much of Asia.
 
A royal name in Scotland, Alexander is still highly popular there. In Gaelic, the name became Alasdair; in Spain, Alejandro; and in Italy, Alessandro.
 
The noble Alexander has led to the popularity of many spinoffs, such as Alex, Zander, Xan and Zan, along with female versions such as Alexandra, Alexis, and the unfortunate Alexa.
 Among the many notable Alexanders in history, standouts are Hamilton, Graham Bell, Fleming, Pope and Haig.
 Naomi Watts and Liev Schreiber's Alexander is known as Sasha.

Alexander

Alexandra fell out of the Top 100 for the first time since 1983 in 2015 but is still a popular choice. Strong, tasteful, and elegant, Alexandra remains a chic modern classic with a solid historic pedigree.
 
Alexandra is the feminine form of Alexander, which ultimately derived from the Greek components alexein, meaning "to defend," and anēr, "man." In Greek mythology, Alexandra was an epithet of the goddess Hera.
 
Alexandra was made fashionable in the English-speaking world by the Danish princess who married England's King Edward VII in 1863, and there have been other royal bearers in both Britain and Russia. Alexandra is the present queen's first middle name. Widely used in Russia, Alexandras can be found in the works of Dostoevsky and Chekhov.
 
International variations include Alessandra and Alejandra. Alexandra offers an array of softer nicknames, from the gender-neutral Alex to the bouncy Lexi to the more dramatic Xandra.

Alexandra

Alexandria turns Alexandra into a more distinctive place-name, in both Egypt and Virginia.

Alexandria

Alexandra is a name with many international variations, elaborations and short forms, and Alexandrine is one of the more unusual.  Another, Alexandrina, was the first name of Queen Victoria.

Alexis, a one-time exclusively-<a href="https://nameberry.com/boys-names">boys’ name</a>, was more popular than its sister Alexandra for quite a while, but in recent years Alexandra has overtaken it once again. Alexis was a Top 20 <a href="https://nameberry.com/girls-names">girls’ name</a> from 1994-2010 but has experienced a decline in popularity in recent years, though now it's one of the <a href="https://nameberry.com/unisex-names">top unisex names</a>.

 Alexis zoomed to popularity following the introduction of the Dynasty character Alexis Carrington in the 1980s – which gave it a sleek image – and was quite popular throughout the 90s and 2000s, peaking at the third most popular <a href="https://nameberry.com/girls-names">girls’ name</a> in 1999.

 One of the few notable female pre-Carrington Alexises was 1940s actress Alexis Smith, who had some minimal impact on the name, which entered the list in 1943. A current bearer is Alexis Bledel, who played Rory on Gilmore Girls and currently stars on The Handmaid's Tale.

An x makes any name cooler, so that Baxter has a bit more pizzazz than the original Baker. Baxter had some currency as a first name a century ago--it was on the popularity lists sporadically from 1880 till the 1920s, peaking at Number 515 in 1886-- which means it's just about due for a comeback. And we can see Bax as a worthy follow-up to Max and Jax.
 Singer Ian Dury named his now-grown son Baxter, and Dr. Baxter Stockman was a scientist in the "Teenage Mutant Ninja Turtle" series. 
 Fun feminist fact: as an occupational name, Baxter was actually the word for a female baker. It's only used for boys now, but could legitimatelt be a unisex name.

Baxter

The jazzy, ultra-cool Dexter, like most names with an "x," has a lot of energy and dynamism. Over the years, it's been attached to a number of diverse real and fictional personalities—C. K. Dexter Haven, the witty Cary Grant character in The Philadelphia Story; Dexter Green, the protagonist of the F. Scott Fitzgerald story "Winter Dreams"; great jazz tenor saxophonist Dexter Gordon; the boy-genius protagonist of cartoon Dexter's Laboratory; and the most recent TV series Dexter based on the books by Jeff Lindsay, whose lead happens to be a genial but sociopathic serial killer.
 Dexter was chosen by hip musical couple Diana Krall and Elvis Costello for one of their twin boys, and by singer Charlotte Church.
 Dex is an equally appealing nickname, now sometimes used on its own.

Dexter

A relatively common surname, Dixon would be an inventive way to honor an ancestral Richard or Dick, the X form a lot livelier than the Dickson spelling, just as Dix is a more modern short form than Dick; it would be right at home alongside Dax and Jax.
 But you don't need us to point out the considerable downside of this name. Besides being a sexual slang term, dick is also the most common epithet describing someone who's a jerk or a meanie (trying to avoid other unsavory words here). And Dix sounds exactly like dicks, which makes it not the least bit easier a name to carry these days than Dick.

Dixon

Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Felix was originally a Roman surname but was adopted as a nickname by the ancient Roman Sulla, who believed that he was especially blessed with luck by the gods. It is the name of four popes and sixty-seven saints; in the Bible, Felix is a Roman procurator of Judea.
 
Felix, energetic and upbeat with a felicitous meaning, has finally transcended its negative associations to Felix The Cat and the persnickety Felix Unger. 
 
The name appears in literature as the central character in George Eliot's novel Felix Holt, the protagonist of Thomas Mann's Confessions of Felix Krull, in Thomas Hardy's Tess of the D'Urbervilles, Henry James's The Europeans, Kurt Vonnegut's Cat's Cradle, and as a member of the Volturi Guard in the Twilight series. In movies Felix has popped up in everything from several James Bond films to Spy Kids and The Hangover.
 
Gillian Anderson and Elizabeth Banks are two modern celebrities who chose Felix for their baby boys. A notable namesake is Felix Frankfurter, a long-term Supreme Court Justice.
 
Popular in the Hispanic community, Felix is also celebrating a surge abroad. Felix has been on the <a href="https://nameberry.com/popular-names">U.S. popularity list</a> for as long as records have been kept and is rapidly becoming a Nameberry fave.

Lennox is an aristocratic and powerful Scottish surname name made truly special by that final x. The worldwide fame of British boxer--World and Olympic champion--Lennox Claudius Lewis brought the name into the spotlight as a first name, while as a last it's tied to Eurythmics singer Annie L.
 The Thane of Lennox appears in Macbeth, Mary Lennox is in The Secret Garden and there are two Agatha Christie characters with the name.
 Lenox is another accepted spelling.

An X-ending surname less common than the Jolie-Pitt-inspired Maddox. Grandparents might still associate it with the old TV crime show.

Max names were one of the hottest trends for boys in the mid-2010s, and are still very popular. The girl versions haven't seen so much love, unfortunately. (Or fortunately, if you love them and want them to stay rare!) Maxima got some attention in 2015 when Mark Zuckerberg and Priscilla Chan used it for their daughter, but few parents have copied them.
The Nissan Maxima is a car model.

Maxima

This name once seemed a bit grand and pompous for an American baby boy, but a significant number of parents are now preferring it as a substantial platform for the nickname Max, among them Jennifer Lopez and Marc Anthony, who chose it for their twin son.
 Maximilian was a traditional royal name among the Hapsburgs in Austro-Hungary and also in Bavaria. In literature, it appears as the husband of Rebecca in the eponymous novel and also in The Count of Monte Cristo. Maximilian Schell was a highly respected Austrian actor who won a Best Actor Academy Award in 1961.

Maximilian

The powerful name of the powerful character played by Russell Crowe in the 2000 film Gladiator first appeared on the popularity charts that same year. Max to the max. One time considered a "too much name" name, Maximus has entered the realm of possibility.
 Maximus was originally a Latin title of honor given to successful military commanders, such as Quintus Fabius Maximus, and then came to be a personal name, borne by several early saints.
 In George Eliot's novel Felix Holt: The Radical, Maximus Debarry is very much an aristocrat. LeBron James used it as the middle name for his son Bryce.

Maximus

With the success of all names Max, from Max itself to Maxwell to Maxfield to Maximilian, it's just possible that Maxine could be lured away from her mah-jongg game at the clubhouse and into the nursery. She's already been chosen by hip musician Nick Hexum for his daughter, sister to Echo.
 Maxine was a Top 100 name from 1915 to 1930, attached to such celebs at the time as actress Maxine Elliott and one of the singing Andrews Sisters, and now to Congresswoman Maxine Waters and Chinese-born writer Maxine Hong Kingston. Reentered the US Top 1000 after a two decade absence in 2016.

Maxine

A happy medium between the weighty Maximilian and the laid-back Max, Maxwell is one of the most classic and attractive <a href="https://nameberry.com/list/428/scottish-baby-names">Scottish names</a>. Early influences on the name's revival include Maxwell Smart of the television show, and then movie, Get Smart, and the Beatles song about Maxwell's Silver Hammer.
 Lance Armstrong chose it for his son, but there was a sharp and unexpected gender switch when both Jessica Simpson and Lindsay Sloane both chose it for their daughters. Still, in the US baby boy Maxwells outnumber baby girls 50 to 1.

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, but when spoken, its negative meaning can't be ignored. 

Effortlessly cool with a hint of the mystical, Phoenix rolls a lot of trends into one: it's a place-name and a bird name, it ends in the stylish letter x, it's got in-built nicknames, and it's unisex too. Familiar but not over-popular, Phoenix ranks in the US and UK Top 1000s.
 
The name Phoenix is associated with an immortal bird from Greek and Egyptian mythology, which having lifted for several centuries would catch fire, then rise from its own ashes. This cycle would endlessly repeat, and therefore, Phoenix is tied to fresh starts, rejuvenation and beginning again after loss. 
 
Phoenix is also linked to the US city in Arizona, named as such because the area was abandoned when settlers found it, and it was seen as a new city born from the ruins of another.
 
Phoenix is a statistically unisex name, though it does tilt slightly towards the boys' side. In 2023, it was given to 1200 boys compared to 860 girls.

A celebrity favorite and a regular feature in pop culture, from Phoenix Wright in video game franchise, Ace Attorney, to a song by the Gorillaz, Phoenix remains an approachable but cool option.

Phoenix

Phoenix is a New Age name symbolizing rebirth and immortality. It's also a place name, a color name, a mythological name, AND an animal name, combining several of today's hottest trends in one appealing package.

Statistically, Phoenix does lean slightly to the boys' side with 1200 boys receiving the name in 2023 compared to 900 girls. Nevertheless, it shares sounds with the familiar Phoebe, Beatrix, and Fiona, as well as Phillip and Felix, and so it doesn't feel out of place on any gender. 
 A celebrity favorite, Scary Spice Mel B, rugby player Mat Rogers, fashion designer John Richmond, and actress Tammin Sursok all chose Phoenix for her daughters.

Castor's twin in the constellation Gemini. That final x makes this name modern and cool.

X marks the spot in names these days, usually at the middles or ends of names, but here is one that puts it squarely up front.
 This extravagant name, which, like many Greek names beginning with X, is pronounced as if it were a Z in English, is derived from the Greek word for the color yellow. A Homeric epithet of Demeter, Xanthe would be a striking choice for a blonde-haired baby girl, thanks to its "golden" meaning.

Xanthe

Xanthia gets this classic Greek name closer to the modern Cynthia, sometimes used as its Anglo equivalent.

That initial X makes even the oldest name feel modern. And using Xanthia as a middle name produces a perfect initial.

Xanthia

Xavier originated is use as a given name after Saint Francis Xavier, cofounder of the Jesuit order, who got his name from the Spanish-Basque village where he was born. His birthplace was Javier, the name of which was derived from the Basque place name Etxeberria, meaning "castle" or "new house." 
 
Many Americans pronounce the initial X, as in ex-ZAY-vee-er, but it's equally accepted to pronounce the name ZAY-vee-er, closer to the French pronunciation.
 
Today's parents are beginning to reassess Xavier, and it's as popular now as it's ever been.
Xavier is one of the only X names most people know and use, often as a middle name following Francis, as in Saint Francis Xavier.
 
Xavier was chosen for their sons by Donnie Wahlberg and Tilda Swinton—as well as for the middle name of Larenz Tate's son Miles and Kim Fields' Quincy. 
 
The Spanish classic Javier, pronounced HAH-vee-ay, has come into greater prominence via Oscar-winning Javier Bardem.
 
Trivia note: the X-men comics introduced the kree8if spelling Xzavier.

Xavier

Xaviera is one of the most intriguing and rarest female forms of a male name. Only a handful of baby girls are named Xaviera in the US each year, compared with nearly 3500 baby boys named Xavier.
 
Why? Xaviera Hollander, the infamous Happy Hooker who penned the1972 bestseller, gave the name a distinctly naughty association, but at this point maybe only to grandma.

Xaviera

The name of a Christian saint and a city in Ohio, Xenia is one of the more accessible and intriguing x names. It is the name of one of the Bond Girls--played by Famke Janssen in the film "GoldenEye." 
 
Sometimes spelled Ksenia to reflect the traditional Greek pronunciation (kseh-NEE-uh), Xenia is also pronounced ZEEN-ee-ah or SHEN-yah.

Xenia

Ximena, sometimes spelled Jimena, is a variation of <a href="https://nameberry.com/boys-names">boys’ name</a> Ximeno. Spanish origins and popularity in the Latino community have boosted this name's popularity. Ximena Diaz was the wife of the Spanish national hero known as El Cid. Several well known Latin American actresses bear this name.
