Vietnamese last names: a guide to the most common

Vietnamese last names come from a surprisingly short list: Nguyễn leads by a wide margin, followed by names like Trần, Lê, Phạm, Hoàng (Huỳnh in the South), Phan, Vũ (Võ in the South), Đặng, Bùi and Đỗ. A small set of family names covers a very large share of the population, so meeting several unrelated Nguyễns in one day is completely normal.

How Vietnamese last names work

A Vietnamese name is written family name first, then a middle name, then the given name. In Nguyễn Văn An, Nguyễn is the family name and An is the personal name. That order matters in daily life, because people are addressed by their given name, not their surname. A teacher named Trần Thị Mai is "cô Mai" (Teacher Mai), never "cô Trần."

Because so many people share a surname, the family name does very little work in conversation. It shows up on official papers, school rolls and wedding invitations, but friends and coworkers almost never use it.

If you want the bigger picture of name order, our guide on how Vietnamese names work walks through all three parts.

The most common Vietnamese last names

Here are the names you will meet most often, with a rough pronunciation hint. The hints follow Northern speech unless noted, and tones are hard to show in English letters, so treat them as a starting point.

• Nguyễn (roughly "nwen" or "ngwee-en," said quickly): by far the most common.
• Trần ("chun," with a falling tone): a major dynasty name.
• Lê ("lay"): also a dynasty name.
• Phạm ("fahm," low and heavy).
• Hoàng / Huỳnh ("hwahng" / "hweeng"): the same family name, split by region.
• Phan ("fahn").
• Vũ / Võ ("voo" / "vaw"): another North and South pair.

Other names you will see regularly include Đặng ("dahng"), Bùi ("boo-ee"), Đỗ ("doh"), Hồ ("hoh"), Ngô ("ngoh"), Dương ("zuhng" in the North, "yuhng" in the South) and Lý ("lee").

Why are so many people named Nguyễn?

The usual explanation is history. Over the centuries, when a new ruling family took power, some people adopted the ruling family's surname, whether to show loyalty, to gain protection or because the name was pressed on them. The Nguyễn were the last imperial dynasty, ruling from 1802 until 1945, and the name had already spread widely before that.

Estimates of how many Vietnamese people carry the name vary by source, but it is commonly described as close to two in five. We dig into the history more in common Vietnamese last names and why so many people are Nguyễn.

Regional pairs: Hoàng and Huỳnh, Vũ and Võ

Some surnames come in Northern and Southern versions. The most cited example is Hoàng becoming Huỳnh in the South. The traditional explanation is a naming taboo: the name Hoàng was avoided in the South out of respect for the Nguyễn lord Nguyễn Hoàng, and Huỳnh was used instead. Vũ and Võ are a similar pair.

This is handy if you are trying to guess where someone's family is from, though it is only a hint. People move, and plenty of Southerners are named Hoàng.

Dynasty names you will recognize

Several of the most common surnames double as the names of royal houses. The Lý, Trần and Lê dynasties all ruled Vietnam before the Nguyễn. If you read Vietnamese history, you will see these names constantly, which is one reason they feel familiar so quickly.

That does not mean everyone named Trần descends from royalty. A shared surname in Vietnam says very little about family connection.

How to pronounce Nguyễn without stress

Nguyễn is the name English speakers worry about most. The "ng" is the same sound as the end of "sing," placed at the start of the word. Many speakers produce something close to "nwen" in casual speech. Southern speakers often say something closer to "ngwin." If you can get the "ng" start, you are already ahead. We give it its own guide in how to pronounce Nguyễn.

Do Vietnamese women change their last name when they marry?

Traditionally, no. A Vietnamese woman keeps her own family name after marriage, and children usually take their father's surname. In the Vietnamese diaspora, practices vary, and some women adopt a spouse's surname for convenience on Western paperwork.

Writing Vietnamese last names on forms

On Western forms, many Vietnamese people move the family name to the end so it lines up with the "last name" box. Others keep the original order. If you are entering someone's name, ask which part is the family name rather than guessing. And keep the diacritics when you can, because Võ and Vũ are different names, and so are Lê and Lệ.

A quick memory trick

If you only remember five, make them Nguyễn, Trần, Lê, Phạm and Hoàng. Between them, you will recognize a large share of the Vietnamese names you meet.

Next time you see a Vietnamese name on a list, look at the first word for the family name and the last word for what to call them.
