Korean Surnames Explained: Kim, Lee, Park and Beyond

If you have spent any time around Korean names, you have noticed something: an awful lot of people are named Kim. Korean surnames work very differently from Western ones, and the story behind them is genuinely fascinating.

The big three

Korea has only a few hundred surnames in common use — and just three of them cover close to half the entire country:

• 김 (Kim) — from the Hanja 金, "gold"
• 이 (Lee) — from 李, "plum tree"
• 박 (Park) — from 朴, "magnolia" (and an old word tied to "brightness")

After those come 최 (Choi), 정 (Jung), 강 (Kang), 조 (Cho), 윤 (Yoon), and a handful of others. Remember that in Korea the surname comes first — 김민준 is Mr./Ms. Kim, given name Minjun.

Clans and ancestral seats

So if half the country is "Kim," are they all related? No — and this is the elegant part. Each surname is divided into clans by ancestral seat, the bongwan (본관): the home region the family line traces back to. So a 김해 김씨 (Gimhae Kim) and a 경주 김씨 (Gyeongju Kim) share a surname but belong to entirely different lineages. The surname alone does not make a family; the surname plus the bongwan does.

Why the spellings look odd

The romanizations can be puzzling, because most are older, traditional spellings rather than strict Revised Romanization:

• 이 → "Lee" — the character 李 once carried an r/l sound that softened away, so it is now said simply "ee," yet often still written Lee or Rhee.
• 박 → "Park" — there is no r sound in 박; the "r" was added long ago to signal a long "ah" for English readers. It is "Pak."
• 최 → "Choi" — written Choi, but closer to "Chwe" than "Choy."

Families guard these spellings as part of their identity, which is why you rarely see them "corrected."

A few more facts

Women in Korea keep their own surname after marriage — a Kim who marries a Park stays Kim. And as with given names, a few surnames are two syllables, like 남궁 (Namgung) and 황보 (Hwangbo).

A Korean surname is less a label than an address in a vast family tree — it tells you not just who someone is, but which ancient line they belong to.

More than a label

It is easy to treat a surname as just the word in front of the given name, but in Korea it carries real freight. The shared sense of clan means two strangers who discover the same surname and the same ancestral seat may genuinely count as distant kin — old custom once even discouraged marriage between them. The family registry, the holiday rituals honoring ancestors, the pride in a clan's long history — all of it threads back through that one inherited syllable. So while half the country may answer to Kim, Lee, or Park, those names are anything but generic to the people who carry them.
