Choi (Korean: 최; Hanja: 崔) is a Korean family surname. As of the South Korean census of 2015, there were around 2.3 million people by this name in South Korea or roughly 4.7% of the population. In English-speaking countries, it is most often anglicized as Choi, and sometimes also Chey, Choe or Chwe. Ethnic Koreans in the former USSR generally prefer the forms Tsoi or Tsoy, especially as a transcription of the Cyrillic Цой.
There are roughly 160 clans of Chois.[citation needed] Most of these are quite small. However, Choi is the 4th most common surname in Korea. The largest by far is the Gyeongju Choi clan, with a 2000 South Korean population of 976,820. The Gyeongju Choi claim the Silla scholar Ch'oe Ch'iwŏn as their founder.

Choi is written with the Hanja character 崔, meaning "a governor who oversees the land and the mountain".
In Korean, 최 is usually pronounced [tɕʰwe] "Chwe" or “Chey” except by some older speakers who pronounce it [tɕʰø] (this vowel sound is similar to the German ö [ø]). In Spanish, it is most often pronounced /ˈtʃɔɪ/ "Choy", which sounds clearly different to its proper pronunciation but some go by “Chey”.
