Origin
Meaning and history of Kingarthur
The name Kingarthur is an English given name that combines the words "king" and "Arthur," referring to the legendary British monarch King Arthur. The name has its origins in medieval times, when stories and folklore about King Arthur and the Knights of the Round Table were widely circulated.
The name Kingarthur reflects the enduring popularity and cultural significance of the Arthurian legends, which have been retold and adapted in various forms throughout history. These legends depict King Arthur as a heroic and chivalrous ruler who defended Britain against Saxon invaders and led his knights on quests for the Holy Grail.
One of the earliest recorded instances of the name Kingarthur is found in the chronicles of Geoffrey of Monmouth, a 12th-century cleric and writer who documented the lives of British kings, including Arthur. His work, "Historia Regum Britanniae" (History of the Kings of Britain), contributed to the widespread dissemination of Arthurian legends and may have inspired the use of the name Kingarthur.
Throughout history, several notable individuals have borne the name Kingarthur. One of the earliest recorded examples is Kingarthur Pendragon (c. 475-542 CE), a legendary British king who, according to legend, was the father of King Arthur. Another prominent figure was Kingarthur Tudor (1491-1502), the eldest son of King Henry VII of England and Elizabeth of York, who died at a young age.
In the 16th century, Kingarthur Plantagenet (1557-1625) was an English nobleman and courtier during the reigns of Elizabeth I and James I. He was known for his involvement in various literary and cultural endeavors, reflecting the enduring fascination with the Arthurian legends during the Renaissance period.
During the 19th century, Kingarthur Tennyson (1809-1892) was a renowned English poet who wrote the iconic "Idylls of the King," a poetic retelling of the Arthurian legends that further cemented the name's association with these stories.
Finally, Kingarthur Conan Doyle (1859-1930), the famous Scottish author and creator of Sherlock Holmes, also bore the name Kingarthur, although he was known by his middle name, Conan.
These examples demonstrate the enduring legacy and cultural significance of the name Kingarthur, which has been shaped by the Arthurian legends and their lasting impact on literature, art, and popular culture over the centuries.

FAQ
Kingarthur: questions and answers
How many people in the U.S. are named Kingarthur?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Kingarthur going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 68,550,868 US residents.
Is Kingarthur a common name?
We classify Kingarthur as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Kingarthur most popular?
The single biggest year for Kingarthur was 2018, when 5 babies received the name. The fact that the average living Kingarthur is about 8 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Kingarthur in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kingarthur a male name?
Yes, 100.0% of people registered as Kingarthur in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Kingarthur still being used today?
Yes. The SSA still recorded Kingarthur in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Kingarthur can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
