How Korean Names Work: Family Names, Given Names, and Why Everyone Seems to Be Named Kim

Korean names follow a completely different structure from Western names. Here's how they work, why there are so few surnames, and how to address people correctly.

If you've watched any Korean content, you've noticed that a huge number of characters share surnames: Kim, Lee, Park. That's not a coincidence. And understanding why tells you a lot about Korean history and culture.

Name structure: surname first

Korean names follow the order: Family name (성) + Given name (이름)

So Kim Jiyeon (김지연) has:

  • Family name: 김 (Kim)
  • Given name: 지연 (Jiyeon)

This is opposite to Western convention, where given names come first. When Koreans introduce themselves in English, they sometimes flip to Western order: sometimes they don't. Pay attention to context.

Why so many Kims?

About 21.5% of South Koreans are named Kim. Lee (이) is about 14.7%, Park (박) about 8.5%. Together, these three surnames cover nearly 45% of the entire Korean population. The reason is historical: traditional Korean society was highly hierarchical, and claiming descent from noble clans (which often had the same surnames) granted social status. During the Joseon dynasty, commoners adopted surnames en masse, often choosing prestigious clan names. After the Japanese occupation ended in 1945, many Koreans who had been forced to use Japanese names reverted to these same common Korean surnames.

Given names: meaning matters

Korean given names are typically two syllables (sometimes one), chosen for their meaning in Hanja (Chinese characters). Parents think carefully about the meaning, sound, and character combination.

Common elements in given names:

  • 준 (Jun): talented, handsome
  • 지 (Ji): wisdom, will
  • 민 (Min): quick, clever
  • 연 (Yeon): lotus, beautiful
  • 현 (Hyeon): wise, virtuous
  • 수 (Su): long life, longevity

Many names are gender-neutral in Hangul: you often can't tell from the name alone.

How to address Koreans

Never use someone's full name in conversation. It sounds extremely rude.

Instead, Koreans use:

  • Job title: 김 선생님 (Teacher Kim), 박 부장님 (Manager Park)
  • 씨 (ssi): polite, casual: 지연 씨, 김 씨
  • 님 (nim): very respectful: 선생님, 고객님
  • 오빠/언니/형/누나: older brother/sister terms used between friends
  • 아/야: used to call close friends (아 after consonant-ending names, 야 after vowel-ending)

Using someone's given name without a title is reserved for very close friends of the same age or younger people under you.

Honorific name suffixes

씨 : Mr./Ms. (used with given name or full name, NOT with surname alone) 올바름: 지연 씨 ✓ / 김지연 씨 ✓ / 김 씨 ✗ (this sounds cold/dismissive)

님 : Lord/Lady (very polite): 고객님 (customer), 선생님 (teacher)

Foreign names in Korean

Korean names are written in Hangul, but foreign names are transcribed phonetically. "Sarah" becomes 사라, "Michael" becomes 마이클. When you introduce yourself to Koreans, they'll try to render your name in Hangul. It's a warm gesture. And learning how to write your own name in Hangul is a satisfying early win.


Names are a window into Korean social structure. The formality system that governs how you address people is the same system that governs how you conjugate verbs. It all connects. A structured Korean course's SNU-based curriculum embeds this cultural context into grammar lessons from the start.
