Understanding Korean Surnames: Kim, Lee, Park and Beyond

The Big Three: Kim, Lee, and Park

Over half of the Korean population carries one of these three surnames. But sharing a surname doesn't necessarily mean being closely related. Each surname is divided into various "Bon-gwan" (ancestral seats), which represent the geographic origin of the clan.

Kim (金) - The Golden Lineage

Kim is the most common surname, with nearly 20% of Koreans carrying it. The two largest clans are the Gyeongju Kim and the Gimhae Kim. The Gyeongju Kim clan traces its roots to the royal family of Silla, while the Gimhae Kim clan originates from King Suro of the Gaya confederacy.

Lee (李) - The Royal House of Joseon

Lee (or Yi) is the second most common surname. The Jeonju Lee clan is perhaps the most famous, as it was the royal family of the Joseon Dynasty for 518 years. Being a Lee was often associated with high social status and scholarly achievement.

Park (朴) - The Gourd Legend

Park is unique because it is a purely Korean surname with no equivalent in China. According to legend, the founder of the Silla Kingdom, Bak Hyeokgeose, was found in a large purple egg that looked like a gourd (Bak).

Rare Surnames and Naturalized Clans

Beyond the major surnames, Korea has hundreds of rare family names like Jegal, Seomun, or Dokgo. Some surnames originated from foreigners who naturalized during the Goryeo or Joseon periods, such as the Vietnam-originated Hwasan Lee clan or the Japanese-originated Sayaka (Kim Chung-seon) clan.

The Modern Significance of Surnames

While the strict class system has disappeared, Koreans still take great pride in their lineage. Knowing one's Bon-gwan is a way to honor ancestors and maintain a sense of belonging in a rapidly changing world.
