Meaning and history of Isaiahs
The name Isaiahs is derived from the Hebrew name Yeshayahu, meaning "Yahweh is salvation". It is the plural form of the biblical name Isaiah, which has roots dating back to the 8th century BCE. This name became popular during the biblical era, particularly in ancient Israel and surrounding regions.
The name Isaiah appears in the Old Testament of the Bible, referring to the prophet Isaiah, who lived in Jerusalem during the 8th century BCE. He was one of the most prominent prophets in the Hebrew Bible, known for his powerful prophetic visions and messages about redemption and salvation.
One of the earliest recorded individuals with the name Isaiahs was Isaiahs ben Malki, a Jewish scholar who lived in the 2nd century CE in ancient Palestine. He was a student of the renowned Rabbi Akiva and is mentioned in the Mishnah, a central text of Rabbinic Judaism.
Throughout history, several notable figures have borne the name Isaiahs. One of the most famous was Isaiahs the Solitary (390-491 CE), an early Christian monk and hermit from Alexandria, Egypt. He was known for his ascetic lifestyle and writings on spiritual matters.
Another significant figure was Isaiahs of Scetis (5th century CE), an Egyptian Christian monk and disciple of Saint Isidore of Pelusium. He was renowned for his wisdom and spiritual guidance, and his teachings were widely circulated in monastic communities.
In the 16th century, Isaiahs ben Abraham Halevi Horowitz (1555-1630) was a prominent Jewish scholar and rabbi from Prague. He was known for his influential works on Jewish law and ethics, including the famous "Shene Luchot HaBrit" (The Two Tablets of the Covenant).

FAQ
Isaiahs: questions and answers
How many people in the U.S. are named Isaiahs?
Name Census puts the figure at roughly 169 living Americans. We arrive at this by taking every SSA birth registration for Isaiahs 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 2,028,132 US residents.
Is Isaiahs a common name?
We classify Isaiahs as "Very Rare". It ranks above 72% of all first names in the SSA dataset by living bearers. Across the full history of the data, 171 babies have been registered with this name.
When was Isaiahs most popular?
The single biggest year for Isaiahs was 2012, when 13 babies received the name. The fact that the average living Isaiahs is about 15 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 Isaiahs in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Isaiahs a male name?
Yes, 100.0% of people registered as Isaiahs 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 Isaiahs still being used today?
Yes. The SSA still recorded Isaiahs 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 Isaiahs 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.
