Origin
Meaning and history of Seidon
The given name Seidon is derived from the ancient Greek word Poseidon, the name of the god of the sea, earthquakes, and horses in Greek mythology. The name is rooted in the Indo-European linguistic tradition and can be traced back to the ancient Greek civilization that thrived between the 8th century BC and the 6th century AD.
Poseidon was one of the principal deities of the Greek pantheon, along with Zeus and Hades. He was widely revered and worshipped in various parts of the ancient Greek world, particularly in coastal regions and islands. The name Seidon is a variation of the original Greek name, which has undergone slight modifications over time.
One of the earliest recorded references to the name Poseidon can be found in Homer's epic poems, the Iliad and the Odyssey, which date back to the 8th century BC. In these works, Poseidon plays a significant role and is depicted as a powerful and formidable deity with the ability to cause earthquakes and control the seas.
Throughout history, there have been several notable individuals who bore the name Seidon or its variations. One of the earliest recorded figures was Seidon of Lesbos, a Greek philosopher who lived in the 6th century BC and was a contemporary of the famous pre-Socratic thinker Thales.
Another prominent figure was Seidon of Corinth, a wealthy merchant and shipowner who lived in the 5th century BC. He was known for his contributions to the development of trade routes and naval technology in ancient Greece.
In the realm of literature, the name Seidon was immortalized by the Greek poet Pindar, who lived from 522 BC to 443 BC. Pindar composed several odes and poems that celebrated the exploits of athletes and rulers, and he frequently invoked the name of Poseidon, the god of the sea, in his works.
During the Byzantine era, there was a notable figure named Seidon of Constantinople, who served as a high-ranking official in the imperial court in the 11th century AD. He was known for his diplomatic skills and played a crucial role in maintaining relations between the Byzantine Empire and its neighboring kingdoms.
In the field of arts and architecture, the name Seidon is associated with the Italian Renaissance sculptor and architect Seidon di Michelangelo, who lived from 1475 to 1564. He was a contemporary of the renowned Michelangelo and contributed to the design and construction of several notable buildings in Rome and Florence.
While the name Seidon has ancient roots and a rich historical background, it has remained relatively uncommon in modern times, particularly in Western cultures. However, it continues to be used in certain regions and communities that have a strong connection to the Greek heritage and mythology.

FAQ
Seidon: questions and answers
How many people in the U.S. are named Seidon?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Seidon 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 Seidon a common name?
We classify Seidon 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 Seidon most popular?
The single biggest year for Seidon was 2015, when 5 babies received the name. The fact that the average living Seidon is about 11 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 Seidon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Seidon a male name?
Yes, 100.0% of people registered as Seidon 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 Seidon still being used today?
Yes. The SSA still recorded Seidon 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 Seidon 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.
