Many names for boys (and girls too) can start with either a C or a K. The C and K spellings have become basically interchangeable. Typically, the K spelling is the variation, although that is not always the case. Names such as Cai and Cale have spawned from Kai and Kale. In some cases, both spellings are equally legitimate, such as with Cillian and Killian, or Caspar and Kaspar.
Along with Kai and Killian, other boy names that can start with a C or a K in the US Top 1000 include Cairo and Kairo, Cash and Kash, Colton and Kolton, and Crew and Krew. Those in which both spellings are rare include Caius and Kaius, Cato and Kato.
The choice of C or K as an initial may reflect your feelings on name style, traditionality, and image. Here, a selection of boy names that work with either C or K as a first letter.
- Kai
Origin:
HawaiianMeaning:
"sea"Description:
Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
- Callum
Origin:
Scottish form of Columba, LatinMeaning:
"dove"Description:
Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal.
- Cillian
Origin:
IrishMeaning:
"war strife or church"Description:
Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.
- Caleb
Origin:
HebrewMeaning:
"dog; whole heart"Description:
Caleb has two potential derivations, the first being from the Hebrew kelev, meaning "dog," and the second from the Hebrew components kal and lev, together meaning "whole heart." In the Old Testament Caleb is one of only two ancient Israelites (Joshua was the other) who set out from Egypt to finally enter the promised land.
- Caius
Origin:
LatinMeaning:
"rejoice"Description:
Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.
- Calvin
Origin:
LatinMeaning:
"bald, hairless"Description:
Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency.

- Cian
Origin:
IrishMeaning:
"ancient"Description:
A handsome Irish name for boys, very popular in that country, but in the US this traditional spelling might cause pronunciation problems. Still, whether Cian or Kian, it's simple and straightforward enough for the initiated. Cian is rising in the British popularity charts. This was the name of several legendary figures, including Cian, son of the god of medicine. His own son was Lugh, the sun god and father of the Ulster warrior Cuchulain and Cian is also the name of the son-in-law of the high king Brian Boru. So very well connected.
- Christopher
Origin:
Greek and LatinMeaning:
"bearer of Christ"Description:
Christopher derived from the Greek Christophoros, which is composed of the elements Christos, referring to Christ, and phero, meaning "to bear." The name was originally used figuratively, to represent the bearing of Christ in one’s heart. Later it became used to honor Saint Christopher, a third century martyr who became the protective saint of travelers, reflecting the legend of Christopher being the giant who carried the Christ Child over a river.
- Cooper

English occupational nameMeaning:
"barrel maker"Description:
The genial yet upscale and preppy Cooper was one of the first occupational last names to catch on -- and Cooper remains a pleasing option.

Origin:
English and Scottish surnameMeaning:
"son of the marsh dwellers"Description:
Carson is one of the most long-running popular androgynous baby names, with a dash of the Wild West via the legendary Missouri frontiersman Kit Carson. Dating back to when it was the name of Nancy Drew's Dad, Carson is still steadily in the Top 100 baby names.Current Carsons include TV personalities Carson Daly and Carson Kressley, and Pro Bowl quarterback Carson Palmer. Carson Wells was the bounty hunter character played by Woody Harrelson in No Country for Old Men, and Carson is the name chosen by actress Kathryn Erbe for her son.
- Carter
Origin:
English occupational nameMeaning:
"transporter of goods by cart"Description:
Carter has been popular for almost two decades, but it only cracked the Top 30 in 2014, leaving the other upscale occupational surname names behind. Having hot characters named Carter on both Gossip Girl and The OC probably didn't hurt, and for fifteen years on ER" Noah Wyle's Dr. John Carter was always called by his last name. Carter also, of course, has presidential cred.

LatinMeaning:
"mild, merciful"Description:
Clement, the name of fourteen popes and several saints, has a pleasantly, positive, slightly antiquated feel, like the phrase "clement weather."
- Kian

"ancient; king"Description:
A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.
- Cain
Origin:
HebrewMeaning:
"spear; possessed"Description:
Biblical name Cain was, until recently, seldom heard outside of the Old Testament and soap operas. Although Cain's murderous actions will always make this name difficult for some, Cain, Eve and Adam's firstborn, was a farmer - making this a good choice for those with farming connections. Long outshone by Abel, Cain is starting to find a broader audience, helped along by homophones Kane or Caine.

- Killian
Origin:

Killian – aka Cillian – is a spirited yet resonant Gaelic name that was borne by several Irish saints and could make a distinctive replacement for the dated Kelly.
