Multiracial people in South Korea, or Multiracial South Koreans (Korean: 혼혈 honhyeol, lit. "Mixed Blood"), are residents or citizens of South Korea who are of only partial Korean descent, often born to one Korean parent and one non-Korean parent.

While intermarriage occurred between Goryeo royals and leading families of the Yuan court during Mongol rule from the 13th century,^[1] a persistent concept of Korea as ethnically and culturally homogenous has prevailed in Korea, and continues as Korean ethnic nationalism.^[2] Multiracial non-royal individuals have lived in Korea since at least the Joseon period,^{[disputed – discuss]} with one of that era's best-known cases being the first descendants of the Byeongyeong Nam clan, founded by a Dutchman who accompanied Hendrik Hamel.^[3] Centuries later, the population of multiracial Koreans, in particular "Amerasian" war babies, rose drastically during and shortly after the Korean War.^[4]

Since the mid-2010s, South Korea has seen a rise in interracial relationships between native Koreans and foreign residents and subsequent births of multiracial children. It is believed that this phenomenon is a result of the popularization of South Korean media abroad (Korean Wave), and its ongoing population crisis.^[5][6]

There are many terms by which multiracial South Koreans are either referred to by monoracial Koreans, or identify with themselves. Below is a list of frequently used terms.

• Honhyeol (혼혈, lit. "Mixed blood") — The most-common term used to identify and refer to individuals of partial Korean heritage. It comes from the Hanja-eo reading of the Chinese word 混血 hùnxiě.
  • Hanbaek-honhyeol (한백혼혈, lit. "Korean-White mixed blood") — A derivative of the term 혼혈 honhyeol used to identify multiracial people of mixed White (European) and Korean descent. The additional "한백" hanbaek is a contraction of the words 한국 (hanguk, lit. "Korea") and 백인 (baegin, lit. "White people").
  • Hanheuk-honhyeol (한흑혼혈, lit. "Korean-Black mixed blood") — Another derivative of the term "혼혈", used to identify multiracial people of mixed Sub-Saharan African and Korean descent. The additional "한흑" hanheuk is a contraction of the words 한국 (lit. "Korea") and 흑인 (heugin, lit. "Black people").
• Hapeu (하프, lit. "Half") — Korean transliteration fo the English word "half" used to describe people of half-Korean origin. Very uncommon.
• Kopino (코피노, Korean-Filipino) — A contraction of the ethnonyms "Korean" and "Filipino", used to refer to Asians of a multi-ethnic Korean and Filipino background.

• Amerasian — An American term used to refer to multiracial people born to an East Asian or Southeast Asian mother and a U.S. military father.
• Afro-Asian — A term used to refer to peoples of mixed Sub-Saharan African and Asian descent.
• Blasian — A more colloquially used term to refer to people of mixed Sub-Saharan African and Asian descent. The term "Blasian" is a portmanteau of "Black" and "Asian". The term was first coined in 2001 by Zak Heaton, a Korean adoptee raised in an African American family. Since then, "Blasian" has become associated with multiracial Afro-Asian individuals, as well as Black and Asian partners in interracial relationships.^[7]
• Eurasian — A term used to refer to people of mixed European (White) and Asian descent.
• Wasian — Also spelled "whasian", "Wasian" is a portmanteau of "White" and "asian, and is used to refer to people of mixed European and Asian ancestry. Similar to how "Blasian" is often used in place of its more formal alternative, Wasian is a colloquial term often used in place of "Eurasian".
