998+ Unique, Rare, and Uncommon Boy Names (with Meanings and Origins)

Reeve is cool and dignified, sophisticated and modern — an excellent combination of assets, and a name being seen as a more masculine and distinctive alternative to Reese.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

Cal is a nickname style name that feels as friendly and calm as it does cool and breezy. While its longer forms have proved more popular over the years, Cal as a stand alone has dropped on and off of the US Top 1000 since the 1880s.

Lars is a perfect candidate for a cross-cultural passport: it has been heard often enough here to sound familiar and friendly, yet retains the charisma of a charming foreigner.

The name of the young Greek sun god, brother to the moon goddess Selene, who rode across the sky each day in a chariot pulled by four horses.

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.

Flint is one of the new macho names on the rise today, part old-school tough guy, part rebel. You won't find a tougher, steelier-sounding name; it's part of a genre on the rise along with cousins Slate, Stone and Steel.

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.

The name of the Greek winged god of sexual love may seem a lot to live up to, but like other deity names, it's on the rise. He appears in DC comics as an ally of Wonder Woman, and is the alias of Marvel's Starfox character. Eros is also the name of an asteroid in our solar system. The name is more popular in Italy, where it's been in the Top 200 in recent years,

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

Foster is one commonly heard last name that makes a fine first. The word foster means "to nourish" — as in "fostering hope", or "fostering a relationship". The only problem with Foster might be its association with "foster child."

Adair has flair, the grace of a Fred Astaire. It's a Scottish surname which came from the first name Edgar.

This Roman Emperor's name has long been considered too grand for an American boy. But in this era of children named Augustine and Atticus, it just may be prime for an unlikely comeback.

Salem is a Biblical place name in Canaan, believed to be the same as Jerusalem, as well as the Massachusetts town famous for its late 17th century witch trials. Salem is also a popular first name in its own right throughout the Arabic world.

Quentin, an offbeat name with lots of character, relates to the Latin for the number five and is by far the subtlest and most usable of the Latin birth-order names, masculine as well as stylish and distinctive. It was borne by a third-century saint and came to England with the Normans.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Cove is an up-and-coming nature name whose cool sound and peaceful image saw it rising for both sexes... until COVID-19 hit. It remained steady in use for boys in 2021, but actually increased for girls, although it remains a seriously rare and distinctive choice for either gender.

Though Darcy is the ultimate Jane Austen hero name, it is rarely used for boys today though it's on the upswing for girls. A shame as it's a handsome, roguish kind of appellation that combines elements of French flair, aristocratic savoir faire, and a soft Irish brogue. And in terms of image, it's one of the quintessential English names for boys.

Winslow, despite its creative connection to the distinguished American painter Winslow Homer, does still retain remnants of the image of a Victorian boy in a sailor suit, making Winston or even just Win a preferable modern choice.

Thatcher is an open and friendly freckle-faced surname, fresher sounding than Tyler or Taylor, that dates back to the days of thatched-roof cottages. It is catching on with modern parents—it reached the US Top 1000 for the first time in 2013.
