Boy Names That Start with K
298 namesBoy
K names for boys have a crisp, energetic sound, and this letter is home to a large number of modern names. Many of them are fresh spellings of familiar sounds. Kaleb is a K spelling of a Hebrew name, Kameron and Karter swap in a K for a more common C, and Kayden, Kaden and Kaiden are three versions of the same popular sound. If you like one of these, it helps to decide early which spelling you prefer.
Older K names come mainly from the Celtic languages. Kevin comes from an Irish saint and a word meaning gentle or handsome, Keegan is an Irish surname, and Kenneth was the name of early Scottish kings. Kyle comes from a Scottish Gaelic word for a narrow strait, and Knox is a Scottish surname. Kai is short and bright and appears in several languages, including Hawaiian, where it means sea. King and Kingston offer a regal note, with Kingston also the name of cities in Jamaica and England.
Because the k sound is so distinct, these names tend to cut clearly through a noisy room. Think about how a K spelling may be read by teachers or relatives, and whether your child will often need to spell the name aloud. Kyler and Kyle, for example, are close enough to be confused.
