Boy Names That Can Start with a C or a K

Cairo is an exciting place name possibility with upbeat o ending and an on-trend first syllable. Debuting in the US Top 1000 in 2015, it has been climbing ever since, and, as of 2023, it is given to more than 1000 babies each year.

Contemporary Kairo fits in with the modern trend of substituting a C for a K initial, and in this case, it works to get you more easily to the cool nickname Kai. In fact, parents in the US and the UK see it as working so well that Kairo took over from Cairo as the preferred spelling of the name back in 2018. Given to nearly 1500 babies each year, Kairo is in the US and UK Top 300.

Kade is a prime example of the new trend for substituting K's at the beginning of traditionally C-starting names.

A brisk and unconventional name that could be a style stand-in for confederates Casey, Chase, Cale, and Cade.

Pronounced KAY-nan, this Old Testament place name has a strong modern feel that blends in with on-trend choices like Carter, Colton, and Kayson, but also with Ezekiel, Jeremiah, and Tobias. Associated in the Bible with "The Promised Land", it is also the name of one of Noah's grandsons.

Cason's entire raison d'etre: It's a rhyming variation on the popular Jason, Mason and Brayson. Casen, Kasen and Kason also have crept into the Top 1000 in recent years.

Jason with a K or Kase with an N or Karson without the R. Kason is one of many similar names that are extremely popular right now.

Kaleb is one of several boys' names starting with k that started life as a classic C name, Caleb. Kevin Federline named his boy Kaleb Michael Jackson.

A once trendy name for girls but that's now in decline, this musical option has actually been slowly and quietly on the rise as a masculine option. Given to 115 boys in 2023, compared to 75 in 2017, it could be an alternative to Caleb or Caiden with a hint of creative flair about it.

Actor Coby Bell gives this short but sweet name a hefty amount of street cred. Can also be spelled Koby or Kobe, as in Kobe Bryant.

Lovers of the name Carter and the Kardashians method of baby naming have popularized this choice, one of many boys' names starting with K that began life as boys' names starting with C. Karter has been in the charts since 2005, riding on the success of the original Carter. Since 2014, Karter has been just inside the Top 200.

This is a name that deserves more attention. Cordell is an occupational name that, through its similarity in sound to Cornell, Denzel, Dashiell, Boswell and Maxwell, feels both on-trend and upmarket.

Whether you think of it as Cale with a K, or a pet form of Kalen or Kaleb, this is just the kind of short, synthetic name finding a lot of favor now, but remember -- it's also the name of a vegetable.

Kato gained a lot of attention during the O. J. Simpson trial via witness Kato Kaelin (born Brian). It is also the name of a fictional character in "The Green Hornet." Spelled Cato, it has a lot more credibility as an ancient name.

Manly almost to the point of macho.

A melodic name that's taking off in the African-American community, along with sound-alikes such as Amari, Jamari, and Damari.

A modern spelling of an already modern sounding name, Kash is a spelling variant of the name Cash. Like Kairo, Karter, Karson, and Krew, that K initial gives it a very 21st century feel.

This Nordic-sounding name is ripe for wider usage, especially as a fresh alternative to Christian or similar-sounding Carl.

An increasingly popular spelling of Carson, Karson feels at home with Kayden, Kieran, and Kai. While the Carson spelling sits just outside the Top 100 and is used three times more often, Karson is still given to around 980 babies each year.
