Korean boy names
Almost every Korean two-syllable name is a sound waiting for characters. Minjun, Jiho and Seokjin have no single meaning — the family chooses the hanja at the register office, so two boys in one classroom can share a name without sharing a definition. Exactly one name on this page escapes that, and it is the most useful contrast Korean naming offers: Haneul, 하늘, sky, which has no hanja and never had any.
None of these 26 names sits in the SSA 2025 top 100, so you will find no rank numbers here. Several have topped the newborn registry in South Korea, which counts births rather than surveying them — a genuinely better statistic, and a completely different country.
Traditional names
Sino-Korean names in the classic mould: two syllables, each answering to a Chinese character that the parents pick and enter on the register. The glosses below are the frequent choices, not the definitions — for any individual bearer, the family register is the only authority.
- JihoonJEE-hoonKorean
Not a jun name, despite the look of it. The ending is 훈 — 勳 “meritorious service” or 訓 “to instruct” — with 志 “will” or 智 “wisdom” in front. The ending clusters heavily in Korean men born between the mid-1970s and 2000.
- SeokjinSUHK-jinKorean
석 can be 石 stone, 碩 eminent, 錫 to bestow; 진 can be 鎭 settled, 珍 treasure, 眞 true. Eminent treasure and steady as stone are both real Seokjins.
- SeunghyunSUHNG-hyunKorean
Often 承 “inherit” or 勝 “victory” joined to 賢 “wise, worthy” or 炫 “to shine” — four defensible readings out of two syllables.
- SeungminSUHNG-minKorean
Usually 昇 “to rise” or 勝 “victory” joined to 敏, quick and sharp-witted.
- MinhoMEEN-hoKorean
敏浩, quick-witted and vast, is the common reading — though 民 “the people” and 昊 “the wide sky” are both in ordinary use for the same sound.
- NamjoonNAM-joonKorean
남 is most often 南, south, which in East Asian naming points at an ancestral place rather than a compass bearing. With 俊, talented. Reads formal in Korea — an eldest son's name.
- JihoJEE-hoKorean
Often 志 “will” or 智 “wisdom” joined to 昊 “the vast sky” or 浩 “abundant”.
- DohyunDOH-hyunKorean
A frequent pairing is 道 “the way” with 賢 “wise, worthy”. The sound tells you nothing on its own.
- DoyunDOH-yoonKorean
道 “the way” with 潤 “to moisten, to enrich” is one common reading of several.
- JuwonJOO-wunKorean
원 may be the most character-crowded syllable in the language: 元 first, 源 a river's spring, 願 a wish, 遠 far, 圓 complete. 柱源 reads pillar and wellspring. Given to daughters as freely as to sons.
- YongYOHNGKorean
Brave, courageous — 勇, read 용 in Korean and yǒng in Chinese. In Korea it works mainly as one half of a longer name rather than alone.
The 俊 family
One character explains a startling share of the modern Korean registry. 俊, read 준, glosses as talented and outstanding; in classical usage a 俊 was the kind of man a government hoped to recruit. It has been the single most popular element in Korean boys' names for two decades, and it works at either end of a name.
- MinjunMEEN-joonKorean
敏俊 reads quick-witted and talented — but 민 can equally be 珉, a jade-like stone, or 民, the people. It sat at the top of the Korean newborn figures through the late 2000s.
- SeojunSUH-joonKorean
서 is a quiet syllable with a good bench behind it: 瑞 auspicious, 序 order and sequence, 舒 unhurried. Joined to 俊.
- HajunHAH-joonKorean
河 “river” or 夏 “summer” set in front of 俊. One of the crop of open, liquid names that took over the registry after 2000.
- YejunYEH-joonKorean
藝 “art” or 睿 “farsighted, sage” joined to 俊.
- JunhoJOON-hoKorean
俊 in the leading position for once, joined to 浩 “vast” or 昊 “the wide sky”.
- JunseoJOON-suhKorean
The same two syllables as Seojun, reversed — Korean does that freely. 俊瑞 reads talented and auspicious.
- JunjyoonChinese
The character on its own: 俊, talented and outstanding. Standing alone it is Chinese practice rather than Korean, where it is a building block.
The woo names
The other great modern block. 우 is usually 宇, the eaves of a roof widened to mean all of space, or 祐 and 佑, help and protection from above. Six of these seven pair it with a first syllable; the seventh puts it in front.
- SiwooSHEE-ooKorean
始 “to begin” or 時 “time” with 宇 or 祐. A registry favourite of the 2010s.
- SunwooSUHN-wooKorean
善, good and virtuous, with 宇 the cosmos, 友 a friend, or 佑 to protect.
- EunwooUHN-wooKorean
恩, grace and kindness — the character in the Korean word for gratitude — joined most often to 宇 or 佑.
- GunwooGUHN-wooKorean
建 “to establish” or 健 “robust” with 宇 or 祐.
- HyunwooHYUHN-wooKorean
賢 “wise” or 炫 “shining” with 宇 or 祐.
- JinwooJIN-wooKorean
眞 “true” or 珍 “treasure” with 宇 or 祐.
- WoojinWOO-jinKorean
The same pair the other way about: 宇 or 佑 in front, 珍 “treasure” or 鎭 “steady” behind.
Pure Korean, and therefore fixed
Korean has two vocabularies — the Sino-Korean layer above, and native Korean words that were never Chinese and have no characters at all. A name taken from the native layer cannot be a sound waiting for a meaning, because the meaning is already there. This is the one on the site.
- HaneulHAH-nuhlKorean
Sky — 하늘, the ordinary Korean word, learned in songs long before school. Native words have no hanja, so there is nothing to choose and nothing to look up: every Haneul means sky. The flagship of the hangul-only name, and unisex.
How Korean naming works
The surname comes first, is nearly always one syllable, and is drawn from a startlingly short list — Kim, Lee and Park between them account for something close to half the population, and a Korean woman keeps her own surname after marriage. The given name is then two syllables, romanised with a hyphen in the official Revised system (Min-jun, Ji-hoon) and written closed up here to match the way Korean names travel in English. The family register carries two columns for it: the hangul, which is compulsory, and the hanja, which is not. South Korea's Supreme Court publishes the list of characters that may go in the second column, extended several times over the decades, and a handsome character outside the list simply cannot be entered. Plenty of families now leave the column blank altogether, which settles the sound and nothing else.
Two forces have shaped what actually gets registered. The first is the dollimja, a generational character written into a clan's genealogy and given to every man of the same rank in the lineage, so that cousins born twenty years apart share a syllable by rule rather than by taste — loosening fast since the 1990s, but the reason older Korean relatives' names rhyme with each other. The second is a change of ear. Boys born in the 1960s and 1970s got closed, consonant-heavy names; their grandsons get open vowels and liquid endings, which is the whole story of Seojun, Hajun and Siwoo. Running alongside both, the hangul-only movement of the 1970s and 1980s argued that Koreans should be able to understand their own names without a character dictionary, and produced Haneul, Iseul (dew), Areum (beauty) and Sarang (love). One last thing English speakers should know: Korean names are not reliably masculine or feminine by sound. Compare the Chinese and Japanese systems on the origins index — Korea borrowed the same characters and then built an alphabet that can do without them.
