My wife and I argued about baby names for the entire third trimester. She had a spreadsheet. I had opinions. Her mother had a fortune teller. My father had a list of family syllables that “must be preserved.” If you have ever named a baby in Korea, you know this exact chaos. I ended up spending way too much time digging into name statistics, cultural trends, and generational shifts, so I am putting everything I learned into one place.
How Korean Baby Naming Works (The Basics for International Readers)
Korean names consist of a family name (성, seong) and a given name (이름, ireum). The given name is almost always two syllables, written with two Chinese characters (한자, hanja), each carrying a specific meaning. The family name comes first. So in the name Kim Seo-yun (김서윤), Kim is the family name, and Seo-yun is the given name.
The choice of hanja is where the real deliberation happens. The syllable “서” (seo) could use dozens of different Chinese characters, each with a different meaning: auspicious (瑞), west (西), writing (書), and more. Parents pick characters with meanings they want for their child, like wisdom, brightness, kindness, or prosperity. This is why you cannot fully understand a Korean name without knowing which hanja were chosen.
Some families follow a generational naming convention called dollimja (돌림자), where one syllable of the given name is shared among all siblings or cousins of the same generation. This tradition is fading among younger parents but still honored in many families, particularly first sons.
Top Girls’ Names Trending in 2025-2026
Based on birth registration data from Korean courts (대법원) and private naming service statistics, these names have been dominating for girls:
1. Kim / Lee / Park + Seo-yun (서윤)
This name has held the top position or near-top for several years running. 서 can use the hanja for “auspicious” (瑞) and 윤 for “to shine” or “soft luster” (潤). The sound is gentle, modern, and easy to pronounce in both Korean and English contexts, which increasingly matters to globally-minded parents.
2. Seo-ah (서아)
A close competitor to Seo-yun, with 아 meaning “elegant” or “beautiful” (雅). The two-syllable softness appeals to parents looking for something feminine but not overly traditional.
3. Ha-yun (하윤)
하 often uses the hanja for “summer” (夏) or “great” (河), combined with the lustrous 윤. This name surged starting in 2023 and has stayed in the top five.
4. Ji-yu (지유)
This one carries a modern, almost philosophical vibe. 지 can mean “wisdom” (智) and 유 can mean “abundant” (裕) or “flowing” (流). Some parents intentionally choose characters meaning “freedom” (自由, jayu), making the name a subtle statement about values.
5. So-yi (소이) / Soi
A newer name that has climbed rapidly. 소 can mean “pure” or “simple” and 이 adds a light, bright quality. The name feels fresh and distinctive without being unusual.
Other Popular Girls’ Names
Ye-won (예원), Yun-seo (윤서), Da-in (다인), Eun-seo (은서), and I-seo (이서) consistently appear in the top 20. There is a clear trend toward soft consonants, open vowel sounds, and two-syllable names that sound graceful when spoken aloud.
Top Boys’ Names Trending in 2025-2026
1. Do-yun (도윤)
The reigning champion for boys’ names. 도 often uses the hanja for “path” or “way” (道), echoing Confucian ideals, while 윤 adds brightness. The name manages to sound both traditional and contemporary.
2. Geon-u (건우)
건 means “strong” or “to build” (建) and 우 means “universe” or “space” (宇). There is a heroic quality to this name that appeals to parents. It also references the Gyeonwu (견우) from the traditional Chilseok legend, the Korean version of the star-crossed lovers story.
3. Seo-jun (서준)
Previously the number-one boys’ name for several years, Seo-jun has been slightly overtaken by Do-yun but remains hugely popular. 준 means “talented” or “handsome” (俊). This was the single most registered boys’ name in the early 2020s.
4. Si-u (시우)
A newer-sounding name with 시 meaning “beginning” or “poetry” (詩) and 우 for “universe” (宇). It has a gentle, artistic quality that resonates with millennial parents who prefer softer masculine names.
5. Ye-jun (예준)
예 for “art” or “courtesy” (禮/藝) and 준 for “talented” (俊). This name balances the artistic with the capable, and its popularity reflects parents wanting names that suggest both sensitivity and competence.
Other Popular Boys’ Names
Ha-jun (하준), Ji-ho (지호), Jun-seo (준서), Hyeon-u (현우), and Min-jun (민준) fill out the top tier. Min-jun was the dominant boys’ name a decade ago but has declined as parents seek less common options.
Naming Trends I Am Seeing
The Gender-Neutral Shift
Several of the trendiest names work for both boys and girls. Ha-yun, Ji-yu, and Seo can be found on both lists. This mirrors a broader cultural shift among younger Korean parents who are less concerned with gendered naming conventions than their own parents were. My sister-in-law named her daughter Hyeon (현) as a single-syllable given name, which twenty years ago would have read as exclusively masculine.
Pure Korean Names (순우리말 이름) Gaining Ground
Not all parents want hanja-based names. Pure Korean names, those that use native Korean words rather than Chinese characters, have been growing. Names like Ha-nul (하늘, meaning “sky”), A-ra (아라, meaning “sea” in old Korean), Bo-ram (보람, meaning “worthwhile”), and Bi-na (비나, meaning “shining”) carry a distinctive poetic quality. These names cannot be written in hanja, which traditionalists dislike but which modern parents see as a feature rather than a bug.
Short and Global-Friendly
Parents are increasingly picking names that foreigners can pronounce easily. Yuna, Mina, Siu, Jiho, and Hana cross cultural boundaries smoothly. I have met parents who explicitly tested their shortlisted names with English-speaking friends before deciding. Considering how international Korean society has become, this is practical rather than pretentious.
Fortune Teller Influence (작명소)
Professional name consultants (작명소, jakmyeongso) are still thriving. These experts analyze the baby’s birth date and time (사주팔자, sajupalja) and recommend names with hanja that balance the child’s elemental composition (오행, ohhaeng: wood, fire, earth, metal, water). Fees range from 100,000 to 500,000 KRW, with celebrity consultants charging even more. My mother-in-law insisted we visit one. The consultant suggested three names, one of which we actually liked, so it worked out. But I have heard stories of parents hating all the suggestions and going with their own choice anyway, then feeling guilty about it for years.
Names to Avoid: Practical Advice
A few things I learned the hard way during our naming process:
- Check the popularity rankings before committing. If you love Seo-jun, know that your son will share his name with three other kids in every elementary school class. Some parents prefer common names (safety in numbers); others find it maddening.
- Say the full name out loud, repeatedly. How does it sound when yelled across a playground? How does it sound in a formal introduction? My wife vetoed one name because it sounded too much like a food item when said quickly.
- Check for unfortunate homophones. Korean has many homonyms. A perfectly nice hanja combination can sound identical to an embarrassing word. Run your candidates past multiple native speakers of different ages.
- Consider the English spelling. If there is any chance your child will live, study, or work abroad, think about romanization. “Hyeok” and “Gwak” are perfectly fine Korean sounds but create confusion in English-speaking environments. This should not be the primary factor, but it is worth a moment’s thought.
- Family politics matter. If your in-laws have strong opinions about dollimja syllables or specific hanja, have that conversation early. Discovering a naming conflict in the delivery room is not ideal. Ask me how I know.

Under Korean law, you must register your baby’s name within one month of birth. There is a fine for late registration, and it creates bureaucratic headaches with health insurance enrollment and the resident registration number. Do not assume you can “figure it out later.” Have at least two or three finalized candidates before your due date. And yes, you can change a name later through the courts, but the process takes months, costs money, and requires a justifiable reason. Getting it right the first time saves everyone grief.
