How to write Dan in Korean
In Hangul, Dan is written 단. The same Hangul syllable is used by 2 different Hanja (Chinese characters): 段, 單. Each character is technically a separate surname with its own clans and ancestry, even though they sound identical and are romanized the same way. The most common by far is 段.
What does Dan mean?
The character 段 means section, segment. 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 Dan?
Dan is rare Korean surname. Just above it in the rankings is Gyeon (1,684) and just below it is Soon (1,237). 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
Dan 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 Dan, and the older McCune–Reischauer system gives Tan. Other spellings you will see in real life include Dahn, Dhan. 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 단.
How to pronounce Dan
Dan (단) is pronounced roughly as the Revised Romanization "Dan" 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".
Is Dan Chinese or Korean?
Both, in a sense — the character is shared, the family is not. Korean surnames were written with Chinese characters for over a thousand years, so nearly every Korean surname has a Chinese (and Vietnamese) reading: 段 is Duàn in Mandarin and Đoạn in Vietnamese. A Korean Dan and a Chinese family with the same character are not related; they simply adopted the same character at different times and places. If someone spells their name "Dan" they are almost certainly Korean, because the Chinese and Vietnamese romanizations look different. See our full guide to Korean vs Chinese last names.
