How to write Jang in Korean
In Hangul, Jang is written 장. The same Hangul syllable is used by 8 different Hanja (Chinese characters): 張, 蔣, 章, 莊, 長, 將, 藏, 場. 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 張.
What does Jang mean?
The character 張 means to stretch, to draw a bow; archer. 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.
Major Jang clans (bon-gwan)
Korean surnames are subdivided by bon-gwan — the ancestral hometown of the clan founder. Two people named Jang from different bon-gwan are considered unrelated. The best-known Jang clans are: Indong Jang, Andong Jang, Deoksu Jang. The place name comes first (for example "Gimhae Kim" means the Kim clan whose founder settled in Gimhae).
How common is Jang?
Jang is a top-10 Korean surname. Just above it in the rankings is Kang (1,269,290) and just below it is Yoon (1,020,564). 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
Jang 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 Jang, and the older McCune–Reischauer system gives Chang. Other spellings you will see in real life include Jhang, Zhang, Jahng, Zang, Jaung. 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 장.
How to pronounce Jang
Jang is pronounced "jahng" (장), sometimes spelled Chang.
Is Jang 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: 張 is Zhāng in Mandarin and Trương in Vietnamese. A Korean Jang 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 "Jang" they are almost certainly Korean, because the Chinese and Vietnamese romanizations look different. See our full guide to Korean vs Chinese last names.
