The Lam surname means forest. It comes from the Chinese character 林, and it reaches America down two separate roads: Vietnamese Lâm, and Cantonese Lam from Guangdong and Hong Kong.
What Does the Surname Lam Mean?
Lam means forest, woods or grove. It is a romanised form of the Chinese character 林, a pictograph of two trees standing side by side, read Lâm in Vietnamese and Lam in Cantonese.
The character is one of the oldest and plainest in the Chinese surname stock. It describes a place rather than a trade or a father, which puts it in the toponymic family: a name taken from the ground a family lived on.
That simplicity is why it travelled so well. Forest is a word every language has, and 林 was borrowed as a surname into Vietnamese, Korean and Japanese naming alongside its Chinese life.
Where the Lam Name Comes From
Lam comes from southern China and from Vietnam. Cantonese Lam families trace to Guangdong province and Hong Kong; Vietnamese Lâm families are concentrated in the Mekong delta and the south. The character’s older Chinese heartland is Fujian.
The Bi Gan tradition
Chinese families surnamed 林 have long claimed descent from Bi Gan, a prince of the Shang dynasty executed for remonstrating with the last Shang king. In the tradition, his pregnant widow fled into a forest and gave birth there, and King Wu of Zhou later conferred the surname 林 on the child, Lin Jian.
Treat this as inherited lineage tradition rather than documented genealogy. It is a story clans carried in their genealogies for centuries, and it tells you what Lin families believed about themselves, not what a record office can confirm.
Guangdong, Hong Kong and the Cantonese Lam
In Cantonese, 林 is pronounced lam, and that is the spelling Hong Kong and Guangdong families put on English documents. It is one of the commonest surnames in Hong Kong, where the government romanisation system fixed Lam in passports, birth certificates and shop signs.
So a Lam from Kowloon and a Lin from Fujian are writing the same surname. The difference is which language the clerk was listening to.
Vietnam and the surname Lâm
Vietnamese surnames were overwhelmingly drawn from Chinese characters during a thousand years of Chinese rule and the centuries of literary Chinese that followed, and Lâm is 林 read in Sino-Vietnamese. Some Lâm families descend from Chinese settlers who assimilated; many do not, and simply carry a name that entered the Vietnamese stock long ago.
There is a third route. Nguyễn dynasty emperors, from Gia Long through Minh Mạng, assigned Vietnamese surnames to the Khmer Krom population of the southern delta, and Lâm was among them, alongside Thạch, Sơn, Kim and Danh. A delta Lâm family may therefore be Khmer in ancestry and Vietnamese only in paperwork.
Spelling Variants and Related Names
The main variants of 林 are Lin (Mandarin), Lam and Lum (Cantonese), Lim (Hokkien and Teochew), Liem (Indonesian), Lâm (Vietnamese), Im, Lim or Yim (Korean), and Hayashi (Japanese).
Lim is the reason most Chinese Singaporean, Malaysian and Indonesian bearers of 林 do not spell it Lam: their ancestors spoke Hokkien or Teochew, and the colonial clerk wrote what he heard. Korean 임 or 림, the Naju and Pyeongtaek Im clans, uses the same character, though a second Korean Im uses 任 and is unrelated. Hayashi is the Japanese reading of 林, but a separate surname tradition with its own origins in Japanese place names.
This is the same one-character, many-spellings pattern described on our Chen surname page, where the dialect romanisation system is set out in full.
Two further wrinkles matter. First, the diacritic: Vietnamese Lâm loses its circumflex at the American immigration desk and becomes plain Lam, which erases the one visible clue that a bearer is Vietnamese rather than Cantonese. Second, a smaller collision: the Chinese surname 藍 or 蓝 (Lan, meaning indigo) is also romanised Lam by some Cantonese and Hakka families. It is a genuinely different name that happens to arrive at the same six letters, the same problem handled on our Wong surname page.
The Lams in America
Lam arrived in America in two main streams: Cantonese speakers from Guangdong and Hong Kong across the nineteenth and twentieth centuries, and Vietnamese refugees after the fall of Saigon in 1975.
The Cantonese stream is the older one. Guangdong villagers came for the goldfields and the railroads, were shut out by the Chinese Exclusion Act, and rebuilt in the enclaves that survived it. Lam names sit thickly in the family associations of San Francisco’s Chinatown, and later in the San Gabriel Valley, where Monterey Park and Alhambra became the first suburbs in America with Chinese-majority commercial districts.
The Vietnamese stream is compressed into a generation. The first wave left in April 1975 by air and by boat; the second, from 1978 onwards, was overwhelmingly ethnic Chinese. Around 450,000 Hoa, the Chinese of Vietnam, were expelled or driven out, most of them Cantonese speakers from Chợ Lớn, Saigon’s Chinese quarter.
That second wave is why the two Lam populations are not as separate in America as the linguistics suggest. A Hoa family from Chợ Lớn is Cantonese by speech, Vietnamese by passport, and Lam either way.
They resettled in the places the sponsorship programmes sent them and then moved to be near each other: Garden Grove and the wider Little Saigon of Orange County, San Jose, and Houston, where the shrimping and refinery economies took Vietnamese families along the Gulf coast.
Vietnamese name order puts the family name first, and Vietnamese speakers address one another by the given name rather than the surname. Both conventions are explained on our Nguyen surname page, and they apply to Lâm exactly as written there.
Notable People Named Lam

How Common Is Lam Today?
Lam is the 611th most common surname in the United States, carried by 55,554 Americans at the 2010 Census. In Hong Kong and Vietnam it is far commoner: 林 is among the top surnames in Hong Kong, and 林 as Lin ranks in the top twenty in mainland China.
| US rank (2010 Census) | #611 |
|---|---|
| Americans with the name | 55,554 |
| Origin | Vietnamese and Chinese (Cantonese) |
| Meaning | Forest, from the character 林 |
The 2010 Census also recorded how bearers described themselves. Of American Lams, 87.99 per cent self-identified as Asian or Pacific Islander, 6.84 per cent as white, 2.56 per cent as Hispanic and 1.99 per cent as two or more races. These are self-identification proportions recorded on a form in 2010, not a measure of anyone’s ancestry, and the Hispanic figure is a real reminder of the Chinese-Cuban and Chinese-Mexican routes that Wifredo Lam’s family took.
Frequently Asked Questions
What does the surname Lam mean?
Lam means forest or grove. It romanises the Chinese character 林, which is drawn as two trees together. The same character gives Vietnamese Lâm, Mandarin Lin, Hokkien Lim and Japanese Hayashi.
Is Lam Vietnamese or Chinese?
Both, and the spelling cannot tell you which. Vietnamese Lâm and Cantonese Lam are the same character read in two languages, so American Lams come from two populations that share a written surname without sharing a recent ancestry. Family memory, not spelling, is what separates them.
Where does the Lam family come from?
Cantonese Lam families come from Guangdong province and Hong Kong. Vietnamese Lâm families come chiefly from southern Vietnam and the Mekong delta. A large group sits in both categories: the Hoa, ethnic Chinese of Vietnam, most of them from Chợ Lớn in Saigon.
How common is the surname Lam?
Lam ranks 611th in the United States with 55,554 bearers at the 2010 Census. Counting every romanisation of 林 together, including Lin, Lim, Im and Hayashi, it is one of the most widely borne surnames on earth.
Is there a Lam family crest or coat of arms?
No. In the heraldic traditions that grant arms, they go to individuals and their direct descendants, never to everyone who shares a surname, and Chinese and Vietnamese naming has no equivalent institution at all. Sites selling a Lam crest are selling a decoration, not a lineage. What Chinese Lin and Lam families did keep is the zupu, the clan genealogy, which is a real record.
Why do some relatives spell it Lin or Lim instead?
Because the surname was romanised from whichever Chinese language the family spoke. Mandarin gives Lin, Cantonese gives Lam, Hokkien and Teochew give Lim. Cousins who emigrated to Singapore and to San Francisco can end up spelling the identical surname two different ways within one generation.
If your family carries the Lam name, its route from Guangdong or the Vietnamese delta to America is traceable. Atlas of Home can follow it from the village or the district of Chợ Lớn to wherever your family landed, and to wherever you are now.
