Origin
Meaning and history of Sairus
The name Sairus is believed to have its roots in the ancient Persian language, originating from the word "Sair," which means "traveler" or "wanderer." This etymology suggests that the name may have been associated with a person who led a nomadic lifestyle or embarked on lengthy journeys.
Historically, the name Sairus can be traced back to the Achaemenid Empire, which ruled over a vast territory spanning from present-day Iran to parts of Central Asia, the Caucasus, and the Mediterranean region. During this period, the name was commonly used among the Persian nobility and aristocracy.
One of the earliest recorded mentions of the name Sairus can be found in the inscriptions of Darius the Great, a prominent Achaemenid king who reigned from 522 to 486 BCE. These inscriptions, carved into the rock at Behistun, mention a rebellious satrap (governor) named Sairus who revolted against the king's authority.
In the realm of ancient literature, the name Sairus appears in the epic poem "Shahnameh" (Book of Kings), written by the celebrated Persian poet Ferdowsi in the late 10th century CE. The poem narrates the legendary exploits of Persian heroes, including a character named Sairus, who is portrayed as a valiant warrior.
Throughout history, several notable figures have borne the name Sairus. One such individual was Sairus of Caria, a Persian general who served under Darius III during the 4th century BCE. He played a significant role in the wars against Alexander the Great and is mentioned in the writings of ancient Greek historians like Arrian and Quintus Curtius Rufus.
Another prominent Sairus was Sairus the Patrician, a Byzantine statesman and military leader who lived in the 6th century CE. He served as a commander under the Emperor Justinian I and is remembered for his victories against the Sassanid Persians and the Ostrogoths in Italy.
In the realm of Islamic history, Sairus ibn Yazid al-Ansari was a prominent Arab general and governor who lived during the 7th century CE. He played a crucial role in the Muslim conquest of Persia and is renowned for his military campaigns against the Sassanid Empire.
Sairus ibn Sahl al-Isfahani was a notable 9th-century Persian mathematician and astronomer who made significant contributions to the fields of algebra and trigonometry. He served as the court astrologer under the Abbasid Caliphate and is credited with introducing several mathematical concepts to the Islamic world.
In more recent times, Sairus Moini was an influential Iranian painter and sculptor who lived from 1932 to 2021. He was celebrated for his contributions to the modern art movement in Iran and his works are displayed in various museums and galleries around the world.

FAQ
Sairus: questions and answers
How many people in the U.S. are named Sairus?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Sairus 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 Sairus a common name?
We classify Sairus 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 Sairus most popular?
The single biggest year for Sairus was 2019, when 5 babies received the name. The fact that the average living Sairus is about 7 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 Sairus in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sairus a male name?

Is Sairus still being used today?
Yes. The SSA still recorded Sairus 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 Sairus 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.
