Keir is a single-syllable name that packs a punch, but also has a endearing quality about it thanks to its similarity to the word care. Sometimes used as a short form of the more popular Kieran, it could be derived from the Irish ciar meaning "black, dark".
 
Alternatively, it may be viewed as a variation of the Scottish Kerr, itself from the Old Norse kjarr, linking it to thicket, marshland, and brushwood. Other sources identify it with keir, an Old Scots word referring to a fort.
 
Notable bearers include Keir Dullea, an American actor who starred in 2001: A Space Odyssey and Sir Keir Starmer, a British politician who was the head of the Labour Party between 2020 and 2026 and the Prime Minister of the UK between 2024 and 2026. 
 
The name ranked in the UK charts back in the 90s and 2000s, but fell out of the stats in 2024, coinciding with Starmer's election. In the US, it has been quietly used since the 1960s and saw a small spike in popularity between 1968 and 1972, around the time of Dullea's star role in 2001: A Space Odyssey. A more recent year saw it given to 7 boys, with Kieran or Kyaire being the preferred options.

Keir

Also written as Kyō, this Japanese name makes a simple, sweet, yet spirited name for a son. Like many Japanese names, the meaning alters depending on which kanji are used, but Kyo can mean "unite, co-operate", "capital city", or "apricot".
 
With the international appeal of Rio and Kai, Kyo appeared in the anime and manga series, Fruits Basket, which may have introduced it to a wider audience.

Predominantly used for boys but occasionally given to girls too, Kayra is a Turkish name that relates to either mythology or to a similar Arabic name. A Top 100 name in its native country, it may be considered a variation of Khayr, relating it to kindness and giving.
 
Alternatively, in Turkish mythology, Kayra is the deity of creation. The ancient Turks did not assign a gender to Kayra, who took the form of a goose. According to legend, Kayra planted the tree of life after creating the universe, from which emerged the nine clans. In this case, it could mean "ruler of the land" or "ruler of the land".

Kayra

Kiefer is a strong occupational surname associated with "24" star Kiefer Sutherland, but one that could well join the other 'er' surnames currently in favor. Keifer is a German surname transferred to first name use, derived from two old Germanic words, kien and forhe, both of which mean "pine tree."
 Kiefer Sutherland, the son of actor Donald Sutherland, was named for director Warren Kiefer, who gave Donald Sutherland his first movie role. Donald was a firm believer in honoring valued friends and mentors--his other sons are named Roeg, Rossif and Angus. Kiefer Sutherland's full name is Kiefer William Frederick Dempsey George Rufus.

 Another possible cultural namesake is the esteemed German artist Anselm Kiefer.

This surprising name was chosen by influencers Morgan Presley and Lou for their son, Krule Enrique, in 2026. A bold choice, perhaps, but less so when you consider their first son is called Pony. 
 
In an Instagram announcement of the name, the couple revealed that they discovered it through the music artist King Krule, who in turn took it from the Elvis Presley movie, King Creole. Other sources claim the artist was inspired instead by the Donkey Kong character, King K. Rool.
 
The name has a variety of different sources, including the Polish surname Król, traditionally used to refer to someone who acted like a king; the Estonian Krull, meaning "hawk"; and the Dutch krul, meaning "curl, twist". Additionally, the aforementioned link to the artist and movie could give it the meaning of Creole.
 
For many English speakers, however, this name would just sound too much like the word cruel, bringing to mind unkindness and brutality. Others may think of crullers, a donut like pastry.

Kubo

This African name, which derives from the Yoruba tribe of Nigeria, is used for both girls and boys -- but in the US, its most notable bearer is (male) artist Kehinde Wiley.  Wiley, who paints brown- and black-skinned people in the style of European Old Masters, was born in Los Angeles of an African-American mother and a Yoruba father and was also a twin, thus his name.  An attractive and creative choice for either gender.

Kester

Téa Leoni and David Duchovny named their kid Kyd in 2002, but he usually goes by his middle name, Miller. Probably a wise choice, given the homonym. On the other hand, the association with Elizabethan playwright Thomas Kyd, who wrote a version of "Hamlet" before Shakespeare, is intriguing. And if you're looking for a name that can't be nicknamed, well... here's looking at you, Kyd.
