Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son back in the 2000s, while actor Kit Connor of Heartstopper fame may have introduced it to a wider audience.

Kit is a crisp, old-time nickname with plenty of spirit and style. In the UK it's a rising star for boys, while in the US, it is trending upwards for girls too.

Kate, in the headlines via Catherine Middleton aka the Princess of Wales, has been as pervasive as Kathy was in the 1950s and 1960s, both as a nickname for Katherine and Kaitlyn and as a strong, classic stand-alone name.

Light and glittery, but with plenty of spirit, Kinsley has risen quickly into the US Top 100. Balanced between preppy and cutesy, it feels like a fresh alternative to Kelly, Kaitlyn, or Kimberly.

Friendly mega-popular short form of Katherine that has definitively replaced Kathy, Katie is often given on its own. Going forward, though, Katie is more stylishly clipped itself to the grownup Kate.

Kimberly's heyday was in the 1960s and 70s, when it ranked among the Top 10. While it hasn't been stylish for decades, it's evidenced more staying power than some former hot girl names, remaining among the Top 300 girl names in the US, where it's stood for 70 years.

Kendra was once seen as a feminization of Kenneth -- but it's now firmly established as a standalone. American parents can't seem to make up their mind about it though: it was one of 2013's fastest-rising names, entering the Top 200 for the first time since 2000, but then it tumbled again.

Originally an English surname, borrowed from the place name, Kendale, Kendall was given almost exclusively to boys until the 40s when it began to be used for a small number of girls each year. By the 80s, it was a gender-neutral choice, however, since the 1993 appearance of the character Kendall Hart in the soap opera All My Children, it has been leaning feminine.

This endearing nickname name is one Katherine pet form that predates all the Kathys and Katies, having been fairly common in the eighteenth century. With the current mini-craze for animal-related names, Kitty is sounding cute and cuddly again—she's already jumped back onto the U.K. list, at number 199.

This punchy surname has some favor in the last couple of decades—potentially due to rapper Kendrick Lamar. It was one of the quickest rising boy names in 2013 when it reached its high point at #318. It has since declined in popularity, but as of 2024, it remains in the US Top 500 and in the UK Top 1000.

Keaton is an engaging surname with warmth, energy and a sense of humor, identified with silent comedian Buster Keaton and contemporary actors Michael and Diane Keaton. Given to around 290 boys in a recent year, it currently sits within the latter end of the US Top 1000.

Chosen for their first son by musical couple Gwen Stefani and Gavin Rossdale, this Jamaican place and elegant British surname also boasts the more regal yet user-friendly short form, King.

Kim is forever feminized, despite memories of the Rudyard Kipling character.

Kingsley is a sophisticated Harry Potter name that entered the US Top 1000 in 2013.

Kent is a no-nonsense, brief, brisk one-syllable name, almost as curt as Kurt.

Kim was the coolest name... of the 1960s. Kim was popularized by actress Kim Novak, and its energy is still maintained by rapper Lil' Kim, but it holds lil' or no appeal for new babies. Parents who like Kim's short, sweet sound might look to a choice such as Sam, Lou, or Belle.

Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.

Yesterday's hottie, today's mom name. Kelsey derives from several English place names and may mean "Cenel's island", from the Old English name Cenel "fierce".

Unisex name around for several decades for boys and now ripe for girls.

A rarely used member of the Ken- family, Kenelm has a rugged, surname-style feel. Borne by a 9th century martyr and a member of the Mercian royal family, it could make an intriguing namesake for a Kenneth, a Kendra, or a Kendrick.
