Origin
Meaning and history of Malachii
The name Malachii is derived from the Hebrew name Malachi, which means "messenger" or "my messenger." It has its roots in ancient Judaic tradition and is found in the Old Testament of the Bible as the name of one of the twelve minor prophets.
The Book of Malachi, the last book in the Old Testament canon, was written by the prophet Malachi around the 5th century BCE. This book addresses the people's lack of faith and calls for a return to religious observance. The name Malachi or Malachii became associated with this biblical figure and his teachings.
One of the earliest recorded uses of the name Malachii can be found in the works of the 1st-century Jewish historian Josephus, who mentions a Jewish high priest named Malachias (a variant spelling) from the 2nd century BCE.
Throughout history, several notable individuals have borne the name Malachii or its variants. One of the most famous was Malachias, an Irish saint and Archbishop of Armagh who lived from 1094 to 1148. He played a significant role in reforming the Irish Church and is regarded as the patron saint of the Diocese of Down and Connor.
Another individual named Malachii was Malachy O'Moore (c. 1094-1148), an Irish prince and warrior who fought against the Anglo-Norman invasion of Ireland in the 12th century. He is remembered for his resistance against the Norman conquest and his efforts to defend Irish sovereignty.
In the 16th century, Malachias Ger was a German Protestant reformer and theologian who lived from 1556 to 1624. He was a prominent figure in the Lutheran Church and wrote extensively on theological matters.
During the 19th century, Malachy Postlethwayt (1800-1868) was a British writer and economist who authored several works on trade and commercial policy.
While not as common as in earlier times, the name Malachii has continued to be used throughout history, often as a variant spelling of the biblical name Malachi. Its connection to the Old Testament prophet and its rich cultural heritage have contributed to its enduring presence across various societies and eras.

FAQ
Malachii: questions and answers
How many people in the U.S. are named Malachii?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Malachii 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 34,275,434 US residents.
Is Malachii a common name?
We classify Malachii as "Very Rare". It ranks above 28.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Malachii most popular?
The single biggest year for Malachii was 2022, when 5 babies received the name. The fact that the average living Malachii is about 3 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 Malachii in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Malachii a male name?
Yes, 100.0% of people registered as Malachii 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 Malachii still being used today?
Yes. The SSA still recorded Malachii 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 Malachii 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.
