Origin
Meaning and history of Kaysan
The name Kaysan originated in the ancient Persian culture, with roots dating back to the 6th century BC. It is derived from the Old Persian word "Kaysan," which means "the one with beautiful eyes." This name was popular among the nobility and aristocracy of the Persian Empire.
During the reign of the Achaemenid Dynasty, which ruled over the Persian Empire from 550 BC to 330 BC, the name Kaysan was often bestowed upon male children born into royal and noble families. It was considered a sign of good fortune and was believed to bring wisdom and clarity to the bearer.
The earliest recorded instance of the name Kaysan can be found in the ancient Persian cuneiform inscriptions at Persepolis, the ceremonial capital of the Achaemenid Empire. These inscriptions date back to the 5th century BC and mention several individuals with the name Kaysan, who were likely high-ranking officials or members of the royal court.
Throughout history, several notable figures have borne the name Kaysan. One of the earliest was Kaysan the Wise, a Persian philosopher who lived in the 4th century BC and was renowned for his teachings on ethics and morality. Another notable Kaysan was a Persian military commander who served under King Darius I in the 5th century BC and played a crucial role in the Persian Wars against the Greeks.
In the 9th century AD, during the Islamic Golden Age, a prominent Persian scholar named Kaysan al-Khorasani made significant contributions to the fields of mathematics, astronomy, and philosophy. He was widely respected for his knowledge and wrote several influential treatises on these subjects.
Another famous Kaysan was a 12th-century Persian poet and mystic who was known for his spiritual verses and teachings on Sufism. His works were widely circulated throughout the Persian-speaking world and had a lasting impact on the development of Persian literature and mysticism.
In the 16th century, a Persian nobleman named Kaysan Khan played a pivotal role in the establishment of the Safavid Dynasty in Iran. He was a trusted advisor to Shah Ismail I and served as a military commander, leading various campaigns to solidify the Safavid rule over Persia.

FAQ
Kaysan: questions and answers
How many people in the U.S. are named Kaysan?
Name Census puts the figure at roughly 289 living Americans. We arrive at this by taking every SSA birth registration for Kaysan 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 1,186,001 US residents.
Is Kaysan a common name?
We classify Kaysan as "Very Rare". It ranks above 78.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 291 babies have been registered with this name.
When was Kaysan most popular?
The single biggest year for Kaysan was 2010, when 25 babies received the name. The fact that the average living Kaysan is about 11 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 Kaysan in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaysan a male name?
Yes, 100.0% of people registered as Kaysan 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 Kaysan still being used today?
Yes. The SSA still recorded Kaysan 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 Kaysan 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.
