Ronin
Masculine · “Masterless samurai”
Ronin is overwhelmingly a boys’ name — 10,272 boys against 222 girls since 1880.
Ronin is a Japanese word before it is an American name: 浪人, written with the characters for "wave" and "person," the term for a samurai left without a lord to serve. It arrived in English-speaking use through screens and pages rather than through family lines, and in the mouth it is straightforward — two even syllables, the same easy shape as Ronan and Owen.
How old is the name Ronin?
Ronin first appears in US birth records in 1998 — 27 years ago. The typical Ronin is a kid of about 7 — this name's wave is very recent. About 10,000 people named Ronin are estimated to be alive in the US today.
When was the name Ronin most popular?
Ronin peaked in 2020, reaching #390 nationally. Today it ranks #504, 114 places below that high. See the whole 2020 chart.

The story of Ronin
The word belongs to feudal Japan, where a samurai whose lord had died or fallen from favor became rōnin — no stipend, no house, no place in the order of things. The most famous such men are the forty-seven rōnin of the Akō incident in the early eighteenth century, whose story was retold on the kabuki stage and in print for centuries afterward. English borrowed the word in the nineteenth century as a term of art, and American readers and viewers met it again through Frank Miller's comic Ronin and John Frankenheimer's film of the same title. Its life as a given name in the United States follows those screen and page appearances, which is why it is carried almost entirely by the youngest generations.
Meaning
Masterless samurai; literally "wave person," a wanderer
The Japanese compound 浪人 (rō, wave + nin, person) described a warrior cut loose from his lord's service. In modern Japanese the same word is used for a student studying for another try at university entrance exams — someone between one station and the next.

The Dangelo test
Every popular name lives one long story — a climb, a peak, a slow settling back. Ronin's later chapters haven't been written yet, so we borrowed them: Dangelo climbed just as high around 1996, and its whole arc is on record. Line the two peaks up, and Dangelo's path sketches the road Ronin is walking now.

The trade-off
- Spelled the way it sounds, and short enough that a child can write it early.
- A word with a documented, traceable meaning in a living language, not a coined form.
- Recognizable well beyond English, since rōnin has been borrowed into film, fiction and games worldwide.
- Two syllables with first-syllable stress, which sits easily against most one- and three-syllable surnames.
- It is a borrowed word with a specific cultural weight. Japanese speakers hear a masterless warrior — or, in current usage, a student sitting out a year between exam attempts. Worth knowing what the word does in the language it comes from.
- Ronin, Ronan and Rowan sit within a letter of each other, so expect a lifetime of gentle corrections, especially in writing.
- Its history as a given name is short, so there are no older bearers to lend it familiarity. In most classrooms it will need introducing once, and then it will be known.
