Origin
Meaning and history of Jasher
The given name Jasher is believed to have its origins in the Hebrew language and culture. The name is derived from the Hebrew word "yashar," which means "upright" or "righteous." It is a relatively uncommon name, but has been recorded throughout history.
One of the earliest references to the name Jasher can be found in the Bible. In the Book of Joshua (10:13) and the Second Book of Samuel (1:18), there are mentions of the "Book of Jasher," which was an ancient text that has been lost to history. This suggests that the name may have been in use during biblical times.
The first recorded person with the name Jasher was Jasher ben Kaleb, a scholar and philosopher who lived in Spain during the 12th century. He was known for his contributions to the study of Jewish law and ethics.
Another notable figure named Jasher was Jasher ben Yehuda, a Jewish poet and philosopher who lived in Spain during the 13th century. He wrote extensively on topics related to Jewish mysticism and philosophy.
In the 16th century, Jasher ben David was a prominent rabbi and scholar who lived in Italy. He was known for his commentary on the Talmud and his teachings on Jewish law.
In the 19th century, Jasher Rosin was a Russian-American author and journalist who was born in 1830. He wrote several books on Jewish history and culture, and was a vocal advocate for Jewish rights in Russia.
Jasher Chassid was a Polish-born American rabbi and author who lived from 1866 to 1945. He wrote extensively on topics related to Jewish ethics and spirituality, and was a respected leader in the Orthodox Jewish community.
While the name Jasher is not as common today as it once was, it has a rich history and has been borne by many notable figures throughout the centuries. Its meaning of "upright" and "righteous" has likely contributed to its enduring appeal among those of Jewish and Hebrew heritage.

FAQ
Jasher: questions and answers
How many people in the U.S. are named Jasher?
Name Census puts the figure at roughly 217 living Americans. We arrive at this by taking every SSA birth registration for Jasher 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 1,579,513 US residents.
Is Jasher a common name?
We classify Jasher as "Very Rare". It ranks above 75.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 219 babies have been registered with this name.
When was Jasher most popular?
The single biggest year for Jasher was 2023, when 24 babies received the name. The fact that the average living Jasher is about 9 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 Jasher in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jasher a male name?
Yes, 100.0% of people registered as Jasher 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 Jasher still being used today?
Yes. The SSA still recorded Jasher 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 Jasher 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.
