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.

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.
- Caleb
Origin:
HebrewMeaning:
"dog; whole heart"Description:
Caleb is an attractive Old Testament name that has been in the US Top 100 for nearly three decades now. Consistently popular but never too popular, Caleb feels more like a classic than a momentary trend.
- Calvin

- Colt
Origin:
Word nameMeaning:
"young horse"Description:
Colt is the kind of unconventionally macho name that is so trendy right now, because of or in spite of its association with horses and guns.
- Caius
Origin:
Variation of Gaius, 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.
- Carson
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 200 baby names.
- 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.
- Cole
Origin:
EnglishMeaning:
"swarthy, coal black"Description:
Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.
- Cade
Origin:
EnglishMeaning:
"round, barrel; battle"Description:
Strong and modern, Cade shot up the popularity lists around the millennium—it was as high as Number 201 in 2001. Now, it has declined in popularity slightly, but nevertheless remains in the US Top 300, given to around 1200 babies each year. Combined with all the baby Kades, Cadens, Kaidens and Kaydens however, it might feel even more popular that it actually is.
- Carter
Origin:
English occupational nameMeaning:
"transporter of goods by cart"Description:
Carter has ranked in the Top 100 since the the turn of the millennium, but despite its recent popularity, it's not a trendy new name. In fact, Carter is one of those names that just misses ranking in the US Top 1000 for its entire 140+ year history.

"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."

"from the coal or dark town"Description:
Colton is a trendy two-syllable choice, with the popular 'on/en' ending.
- Camden
Origin:
American and British place-name, ScottishMeaning:
"winding valley"Description:
Camden is a surprise hit, probably as a result of some star baby cred: it has been chosen by no less than four celebrity parents since 2012. Gentle but not flimsy, Camden could be an updated spin on Cameron, Callum, or Caden.

English word nameMeaning:
"a band or force of armed men"Description:
Crew is yet another word name that was added to the baby name lexicon when this one was chosen by The Young and the Restless star Joshua Morrow for his son. It debuted on the Top 1000 in 2010. We've also heard spelling variations Cru and Crue.
- Killian
Origin:
IrishMeaning:
"war strife or church"Description:
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. Kylian is another spelling that's gaining traction, thanks to French soccer star Kylian Mbappé. Possible downsides: an unsavory first syllable and a connection to the trendy brew.

Irish; PersianMeaning:
"ancient; king"Description:
A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.
