Origin
Meaning and history of Isayiah
The name Isayiah has its roots in the Hebrew language and can be traced back to ancient times. It is a variant spelling of the biblical name Isaiah, which means "Yahweh is salvation" or "the Lord is salvation." The name likely originated in the 8th century BCE, during the reign of the Israelite kings.
One of the most significant historical references to this name is found in the Book of Isaiah, which is part of the Hebrew Bible and the Old Testament of the Christian Bible. The Book of Isaiah is attributed to the prophet Isaiah, who lived in the 8th century BCE and served as a prominent figure during the reign of King Hezekiah of Judah.
The earliest recorded examples of the name Isayiah can be found in ancient Hebrew texts and scriptures. However, it is worth noting that the spelling "Isayiah" is a more modern variation, while the traditional spelling in Hebrew is "Yeshayahu" or "Yisha'yahu."
Throughout history, several notable individuals have borne the name Isayiah or its variants. One of the most famous is the biblical prophet Isaiah himself, who lived around 700 BCE and is revered by Jews, Christians, and Muslims alike for his prophetic teachings and writings.
Another notable figure with this name is Isayiah Thomas (born 1961), an American former professional basketball player and coach. He played for the Detroit Pistons in the NBA and was inducted into the Naismith Memorial Basketball Hall of Fame in 2000.
Isayiah Mustafa (born 1974) is an American actor and former football player, best known for his portrayal of the iconic "Old Spice Guy" in a series of popular commercials for Old Spice body wash.
Isayiah Murietta-Golding (born 1995) is a Canadian actor and model, known for his roles in films such as "The Call of the Wild" and "Honey Bee."
Isayiah Larue (born 1993) is an American professional basketball player who currently plays for the Portland Trail Blazers in the NBA.
It is worth noting that while the name Isayiah has been used throughout history, its popularity has varied across different regions and time periods. However, its biblical origins and connection to the prophet Isaiah have ensured its enduring presence in many cultures and religions.

FAQ
Isayiah: questions and answers
How many people in the U.S. are named Isayiah?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Isayiah 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 57,125,723 US residents.
Is Isayiah a common name?
We classify Isayiah as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Isayiah most popular?
The single biggest year for Isayiah was 2005, when 6 babies received the name. The fact that the average living Isayiah is about 21 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 Isayiah in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Isayiah a male name?
Yes, 100.0% of people registered as Isayiah 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 Isayiah still being used today?
Yes. The SSA still recorded Isayiah 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 Isayiah 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.
