# Ng (name)
**Ng** is a surname romanized from several distinct Chinese family names: most commonly the [Cantonese](https://www.edgepedia.org/cantonese) romanization of 吳 (Mandarin Wu), from the ancient state of Wu; also of 伍 (Mandarin Wu), meaning "five"; and, in Teochew communities, of 黃 (Mandarin Huang).[1](https://onomaverse.com/last-names/ng) • [2](https://www.ancestry.com/last-name-meaning/Ng) It is also recorded as a variant romanization of the surname 鄞.[2](https://www.ancestry.com/last-name-meaning/Ng) With no vowel letters, it is among the shortest surnames in the world, and its spelling signals the bearer's ancestral dialect as reliably as the character itself.[1](https://onomaverse.com/last-names/ng)

## The characters behind the spelling
The same English spelling covers different Chinese surnames, which is the central fact anyone researching an Ng ancestor must confront. In Cantonese, 吳 is pronounced ng⁴ and 伍 is ng⁵, and both are conventionally written Ng in Hong Kong and the Cantonese diaspora.[6](https://cantowords.com/dictionary/%E5%90%B3) • [7](https://zh.wiktionary.org/zh-hans/Ng) The character 吳 is one of the oldest Chinese surnames, traced to the state of Wu during the [Zhou dynasty](https://www.edgepedia.org/zhou-dynasty) (1046–256 BC) in present-day Jiangsu province.[1](https://onomaverse.com/last-names/ng) The character 伍 means "five" and is said to derive from an ancient military unit of five soldiers.[1](https://onomaverse.com/last-names/ng)
A further complication comes from southern China. In Teochew communities, Ng renders the surname 黃 ([Huang](https://www.edgepedia.org/huang-surname) in Mandarin), and the same romanization may also be a variant of 鄞.[2](https://www.ancestry.com/last-name-meaning/Ng) A Singapore commentary on surname heritage notes that someone surnamed Ng there is probably Teochew or Hokkien, and that for these speakers Ng, like Ooi, Wee, Wong, and Bong, is a dialect rendering of the single surname Huang.[8](https://www.channelnewsasia.com/today/voices/local-chinese-surnames-part-singapores-rich-heritage-5512281) In Mandarin pinyin, both 吳 and 伍 are written Wu, so a single family character can appear as Wu, Ng, Goh, Ngo, or Woo depending on which dialect and migration route produced the family's paperwork.[4](https://lingnanarchive.com/surname/wu-ng/)
## Why the spelling sticks
Romanization of Chinese surnames into English generally followed the ancestral dialect rather than Mandarin. When a surname appears as Tan, Lim, Ong, Goh, Ng, or Yap, this spelling can reflect a southern Chinese pronunciation instead of how the same character would be rendered in modern Mandarin.[9](https://www.surnameorigin.org/articles/how-chinese-surnames-change-across-dialects-and-romanization-systems/) This is why the spelling Ng is common in Hong Kong, Malaysia, and Singapore, while the same character writes Wu in mainland China and Taiwan.[4](https://lingnanarchive.com/surname/wu-ng/) • [10](https://wrap.warwick.ac.uk/id/eprint/49816/1/WRAP_THESIS_Tzeng_2012.pdf)
The name is also hard for outsiders to say. The initial sound is a syllabic nasal, the "ng" of "sing" standing alone at the start of a word, and Cantonese preserves this sound as a standalone word, making Ng one of the shortest and most distinctive surnames in the world.[1](https://onomaverse.com/last-names/ng) In the Philippines, the pronunciation of Ng is influenced by the Tagalog particle ng.[11](https://plainspell.com/en/word/ng)
## Distribution
**Where the name concentrates.** Forebears counts about 524,898 bearers worldwide and places the surname 1,022nd globally.[3](https://forebears.io/surnames/ng) Malaysia leads in absolute numbers with 209,849 bearers, followed by Vietnam (99,256), the United States (42,743), Singapore (42,558), and Hong Kong (37,978).[3](https://forebears.io/surnames/ng) Relative to population, Singapore has the highest density, one bearer per 129 residents; Malaysia and Hong Kong follow at 1 in 141 and 1 in 193.[3](https://forebears.io/surnames/ng) Distribution figures from comparable sites differ because of different underlying databases: one profile places Hong Kong first at 37.2 percent of bearers, ahead of Malaysia at 32.3 percent and Singapore at 23.1 percent.[1](https://onomaverse.com/last-names/ng)
**In the United States.** The 2010 Census recorded 31,210 bearers, ranking Ng 1,125th.[12](https://en.wiktionary.org/wiki/Ng) By the 2020 decennial surname tables the count was 32,518, rank #1,060, at 10.88 per 100,000 residents, about 1 in 9,192 Americans; both the raw count and the population-adjusted frequency rose between 2010 and 2020.[5](https://howmanyofme.org/last-names/ng/) In the 2020 Census, 91.06 percent of bearers self-identified as Asian/[Pacific Islander](https://www.edgepedia.org/pacific-islander), with Two or More Races at 3.56 percent and White at 2.54 percent.[5](https://howmanyofme.org/last-names/ng/)
## Family history
The Teochew form of the surname, Ng for 黃, is found in eastern [Guangdong](https://www.edgepedia.org/guangdong) province, from which people migrated to Malaysia, Thailand, Singapore, and other parts of Southeast Asia.[2](https://www.ancestry.com/last-name-meaning/Ng) Among noted bearers, Ng Poon Chew, born in south China in 1866, followed relatives to California and rose to prominence as a promoter of [Chinese culture](https://www.edgepedia.org/chinese-culture) among Americans and of American ingenuity among the Chinese; his surname Ng Poon began appearing on the United States west coast in the 19th century.[13](https://www.familysearch.org/en/surname?surname=Ng) For genealogical research, specialists advise that the first step is confirming which Chinese character the family uses, since the English spelling alone does not determine the lineage.[14](https://www.oldwesthistory.net/blog/wu-vs-ng-surname)
