Origin
Meaning and history of Lothario
The given name Lothario originated in Italy during the 17th century. It is derived from the Italian word "lottare," meaning "to struggle" or "to fight." The name gained popularity after the character of the same name appeared in the 1665 play "The Libertine" by Nicolas Rowe.
In the play, Lothario is depicted as a notorious seducer of women. This characterization led to the word "lothario" becoming a byword for a promiscuous or unscrupulous man who seduces women. The name itself, however, predates this association and has a different meaning entirely.
One of the earliest recorded instances of the name Lothario can be found in the 12th century with Lothario de' Conti di Segni, who became Pope Innocent III in 1198. He was a pivotal figure in the Catholic Church and played a significant role in the Fourth Crusade.
Another notable Lothario was Lothair I, also known as Lothair the Pious, who was the Holy Roman Emperor from 817 to 855 CE. He was the son of Louis the Pious and inherited the Middle Frankish territories after his father's death.
In the 16th century, Lothario Sarsi was an Italian mathematician and astronomer who made contributions to the field of optics and participated in the famous debates between Galileo Galilei and the Jesuits over Galileo's support for the Copernican theory.
Lothario Soulès Bassac, born in 1909 and died in 1988, was a French painter and illustrator known for his work in the Surrealist and Fantastic Realism movements.
Lothario Bluteau, a Chilean actor born in 1957, has appeared in numerous films and television shows, including "The Twilight Saga: New Moon" and "Paz."
While the name Lothario may have acquired a negative connotation due to its association with the promiscuous character in Rowe's play, its origins and historical usage suggest a more diverse and complex meaning. The name has been borne by notable figures across various fields, including religion, politics, science, and the arts.

FAQ
Lothario: questions and answers
How many people in the U.S. are named Lothario?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Lothario 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 Lothario a common name?
We classify Lothario 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, 6 babies have been registered with this name.
When was Lothario most popular?
The single biggest year for Lothario was 1965, when 6 babies received the name. The fact that the average living Lothario is about 64 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 Lothario in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Lothario a male name?
Yes, 100.0% of people registered as Lothario 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 Lothario still being used today?
Yes. The SSA still recorded Lothario 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 Lothario 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.
