Half of all Koreans share just three surnames. There are only 191 Korean last names with five or more holders, yet they split into thousands of clans, each with its own ancestral home. This page is a complete, census-based guide: type any surname into the checker, browse the full ranked table, and follow the links to every surname’s own page.
Korean last names at a glance
- Kim (김), Lee (이) and Park (박) are carried by 44.6% of South Koreans — 22.2 million people out of 49.7 million.
- The top ten surnames cover 65.8% of the population. By comparison, the ten most common surnames in the United States cover about 5%.
- Almost every Korean surname is one syllable. Only 13 two-syllable surnames exist, and together they account for fewer than 60,000 people.
- Korean surnames are written in Hangul (the Korean alphabet) but each also has a Hanja (Chinese character) that carries its meaning — Kim 金 means “gold”, Lee 李 means “plum tree”, Park 朴 means “gourd”.
- Koreans put the family name first: in “Kim Yuna”, Kim is the surname. Women keep their surname after marriage.
- The same surname is subdivided by bon-gwan — the clan’s place of origin. A Gimhae Kim and a Gyeongju Kim are not considered relatives.

One detail that surprises people: by Hangul spelling, Jung (정) edges out Choi (최) for fourth place. The widely quoted “Kim, Lee, Park, Choi, Jung” order counts only the main Hanja 鄭; when you add the smaller Jung lineages written 丁 and 程, the syllable 정 has 2.41 million holders against Choi’s 2.34 million.

How Korean surnames work
A Korean name has two parts: a one-syllable family name followed by a given name that is usually two syllables, as in Kim Yu-na or Park Ji-sung. Because the surname is so short and so widely shared, the given name does most of the work of identifying a person; Koreans are rarely addressed by surname alone. In formal settings a title follows the full name (Kim Yu-na ssi) and in offices the job title replaces the name altogether. Our guide to how Korean names work covers name order, generation names, hyphenation and why Koreans have no middle names.
Each surname is also tied to a clan seat, the bon-gwan. There are about 280 Kim clans alone; the largest, the Gimhae Kim, has over four million members and traces itself to King Suro of Gaya. Until 1997 South Korean law prohibited marriage between people of the same surname and bon-gwan, a rule that a Constitutional Court ruling and the 2005 family law revision removed.
Why are there so few Korean last names?
Three historical forces compressed Korea’s surname pool. First, surnames began as a royal and aristocratic privilege: the Silla kings were Kim, Park and Seok, and for centuries most commoners had no surname at all. Second, when Goryeo’s founder Wang Geon (918–943) rewarded loyal families with surnames and clan seats, he drew on a small stock of prestigious Chinese-character names, and later commoners who acquired surnames copied the same handful. Third, the abolition of the class system in the 1894 Gabo Reform and the compulsory civil registration of 1909 forced every remaining household to declare a surname, and the safest choice was to take the name of the local landowning family, which was most often Kim, Lee or Park. The result is a country where a surname tells you almost nothing about who someone is related to, which is exactly why the bon-gwan system matters so much.
What Korean last names mean
Because Korean surnames were recorded in Chinese characters for over a thousand years, their meanings are the meanings of those characters. Many are ancient Chinese states (Cho 趙, Jung 鄭, Oh 吳, Han 韓), some are natural objects (Lee 李 plum tree, Yoo 柳 willow, Ha 河 river, Seok 石 stone), a few are virtues or qualities (Ahn 安 peace, Choi 崔 lofty, Kang 康 health), and a handful are colours (Baek 白 white, Hwang 黃 yellow). Koreans do not usually think about these meanings day to day, but they matter for genealogy and for the traditional practice of choosing given-name Hanja that harmonise with the surname. Every surname page on this site gives the Hanja and its meaning.
Rare Korean last names
At the other end of the table, 70 surnames have fewer than a thousand holders and 40 have fewer than a hundred. Some are ancient Korean names that simply never grew (Gwok 궉, 183 people), some are Chinese-origin surnames that arrived with a single immigrant family (Mangjeol 망절, 8 people), and a few entered the register in the twentieth century from Japanese families who naturalised (Hwangmok 황목, 5 people). The rarest surnames in the 2015 census:
Two-syllable Korean surnames
Thirteen Korean surnames have two syllables. The best known are Namgung (남궁), Hwangbo (황보), Jegal (제갈), Sagong (사공) and Sunwoo (선우). Most are Chinese compound surnames that came to Korea in the Goryeo period; a Korean will often assume someone named Namgung or Jegal has an unusual family history.
Korean or Chinese? Shared surnames
Because Korean, Chinese and Vietnamese surnames share the same Chinese characters, the same family name can appear in all three countries under different spellings: 李 is Lee in Korea, Li in China and Lý in Vietnam; 金 is Kim, Jin and Kim; 張 is Jang (or Chang), Zhang and Trương. The spelling usually gives away the origin — a “Lee” or “Kim” is almost always Korean, a “Li” or “Jin” Chinese. The families are not related; they adopted the same character independently. Our guide to Korean vs Chinese last names works through the 30 most-confused names.

Frequently asked questions
What is the most common Korean last name?
Kim (김, 金) is the most common Korean last name. 10,689,967 people — 21.5% of South Korea — had the surname Kim in the 2015 census. Lee (14.7%) and Park (8.4%) are second and third.
How many Korean last names are there?
The 2015 South Korean census recorded 191 Korean surnames (by Hangul spelling) with five or more holders, written with 514 different Hanja. The census also counted about 5,500 surnames in total once foreign surnames of naturalised citizens are included, but only a few hundred of those are traditional Korean names.
Do Korean last names come first?
Yes. In Korean the family name comes before the given name: Kim Yu-na’s surname is Kim. Many Koreans reverse the order in English-language contexts, which is why you will see both “Kim Yu-na” and “Yuna Kim”.
Do Korean women change their last name when they marry?
No. Korean women keep their birth surname after marriage. Children traditionally take the father’s surname, although since 2008 parents may agree to give a child the mother’s surname instead.
Why do so many Koreans have the same last name?
Surnames were originally reserved for royalty and nobility, and when commoners acquired them — mostly between the 15th century and the compulsory registration of 1909 — they overwhelmingly chose the prestigious names of the ruling clans: Kim, Lee and Park. The pool of names never widened afterwards.
Are Korean last names the same as Chinese last names?
They share Chinese characters, not families. Kim 金 and Chinese Jin 金 use the same character but are unrelated lineages. The romanized spelling usually reveals the origin: Kim, Lee and Park are Korean; Jin, Li and Piao are the Chinese readings of the same characters.
