Bi 비 — Korean last name
Is Bi a Korean last name?
Yes. Bi (Hangul: 비, Hanja: 丕) is a Korean family name recorded in the 2015 South Korean census with 16 holders, making it the #178 most common of the 191 surnames counted. Roughly one in every 3,106,604 South Koreans is a Bi. It is one of the rarest surnames in Korea — fewer than a thousand people carry it.
How to write Bi in Korean
In Hangul, Bi is written 비. Its Hanja (Chinese character) is 丕. Unlike many Korean surnames, Bi has a single Hanja form, so every Bi in Korea shares the same character.
What does Bi mean?
The character 丕 means great, grand. As with most Korean surnames, the meaning comes from the Chinese character rather than from the Korean sound, so it says something about how the name was first written down (often a place, a virtue, an object or a Chinese dynasty) rather than describing the family. Koreans rarely think about the literal meaning of a surname in daily life, but it matters for genealogy and for choosing given names that pair well with it.
How common is Bi?
Bi is ultra-rare Korean surname. Just above it in the rankings is Bo (16) and just below it is Mu (15). For comparison, Kim, the most common surname, has 10,689,967 holders. All figures come from Statistics Korea's 2015 Population and Housing Census, which only counts surnames held by five or more people.
Spellings and romanization
Bi is the spelling most Korean families use on passports and in English. The official Revised Romanization (used by the South Korean government since 2000) is Bi, and the older McCune–Reischauer system gives Pi. Other spellings you will see in real life include Vy, Vi, Bie, Bee. The variety exists because Korean passport rules let each family choose its own romanization, so spellings drifted over generations of emigration; in Korean, every one of these is the same 비.
How to pronounce Bi
Bi (비) is pronounced roughly as the Revised Romanization "Bi" reads, with even stress on each syllable — Korean does not stress one syllable over another the way English does. Vowels are pure and short: "eo" is the "u" in "sun", "eu" is a tight "oo" with unrounded lips, and "ae" rhymes with "day".
