In general, a Vietnamese pronoun (Vietnamese: Đại từ nhân xưng, lit. 'Person-calling pronoun', or Vietnamese: Đại từ xưng hô) can serve as a noun phrase. In Vietnamese, a pronoun usually connotes a degree of family relationship or kinship. In polite speech, the aspect of kinship terminology is used when referring to oneself, the audience, or a third party. These terms may vary by region. Many are derived from Chinese loanwords but have acquired the additional grammatical function of being pronouns.

Vietnamese terms of reference can reveal the social relationship between the speaker and the person being referred to, differences in age, and even the attitude of the speaker toward that person. Thus a speaker must carefully assess these factors to decide the appropriate term. Strangers may ask each other about age when they first meet to establish proper terms of address. If the speaker does not know the listener, there is a certain pronoun that they can address the speaker to sound respectful.^{[clarification needed]}

True pronouns are categorized into two classes depending on if they can be preceded by the plural marker chúng, bọn, or các. Like other Asian pronominal systems, Vietnamese pronouns indicate the social status between speakers and others in the conversation in addition to grammatical person and number.

The table below shows the first class of pronouns that can be preceded by a pluralizer. The parenthetical information next to these pronoun forms indicates information about the social status between the speaker and another person (or persons). Thus, "inferior to superior" indicates that the speaker is in an inferior or lower social status with respect another person (such as the hearer) who is in a superior or higher social status. The label "familiar" indicates that the speaker and another person are in a closer relationship such as between family members or between close friends. The label "intimate" refers to a very close relationship such as that between spouses or lovers.

Tôi was an archaic noun meaning "servant", as in vua tôi ("the monarch and his servants"). There are parallel self-deprecating first-person pronominalizations of words for "servant" in other languages, such as 奴 (nù) in Eastern Min and 僕 (boku) in Japanese. Tôi is often used formally and conveys the connotation of equal status, regardless of age. Another word with the same semantic development is tớ, although it is used informally among similarly aged peers.

Mình is still used as a noun with its original meaning, "body". It is also used as a reflexive pronoun in all persons. For example, Tôi biết mình không giỏi ("I know I (myself) am not good"), Nó tự hỏi mình ("They ask themself").

The first person tôi is the only pronoun that can be used in polite speech. The first person ta is often used when talking to oneself as in a soliloquy, but also indicates a higher status of the speaker (such as that of a high official, etc.). The other superior-to-inferior forms in the first and second persons (tao, mày, mi, bay) are commonly used in familiar social contexts, such as among family members (e.g. older sister to younger sister, etc.). These forms are otherwise considered impolite,^[1] and various forms of pronoun avoidance such as using kinship terms are used instead. The third person form nó (used to refer to animals, children, and scorned adults, such as criminals) is considerably less arrogant than the second person forms tao, mày, mi, bay. The pronoun mình is used only in intimate relationships, such as between spouses.

The pronominal forms in the table above can be modified with chúng as in chúng mày, chúng nó. Exclusive/inclusive plural distinctions exist in the first person: chúng tôi and chúng tao are exclusive (i.e., me and them but not you), chúng ta and chúng mình are inclusive (i.e., you and me). Some of the forms (ta, mình, bay) can be used to refer to a plural referent, resulting in pairs with overlapping reference (e.g., both ta and chúng ta mean "inclusive we").

The other class of pronouns are known as "absolute" pronouns.^[2] These cannot be modified with the pluralizer chúng. Many of these forms are literary and archaic, particularly in the first and second person.

Unlike the first type of pronoun, these absolute third person forms (y, hắn, va) refer only to animate referents (typically people). The form y can be preceded by the pluralizer in southern dialects in which case it is more respectful than nó. The absolute pronoun người ta has a wider range of reference as "they, people in general, (generic) one, we, someone".^[4]

Kinship terms are the most popular ways to refer to oneself and others. Anyone can be referred to using kinship terms, not just the speaker's relatives. The Vietnamese kinship terms are quite complex. While there is some flexibility as to which kinship terms should be used for people not related to the speaker, often only one term applies to people related by blood or marriage, for up to three generations. Some kinship terms are:

Except the terms for "father", "mother" and "child", all others, such as "elder brother", "elder sister", "younger sibling", "uncle", "aunt", "nephew/niece/grandchild", etc. are usable for cousins, and cousinship is inherited from older generations and through marriage. In this regard, grandparents, aunts and uncles, nieces and nephews, etc. are a kind of closer "cousins" to the speaker; the further a relative is, the further back the speaker has to trace in order to know exactly if they should use "grandpa", "grandma", "uncle", "aunt", etc. Distant cousins with "grandparent status" that are younger than the speaker may be referred to as ông/bà trẻ ("young grandpa/ma"). This phenomenon is highlighted in a Vietnamese proverb: Bé bằng củ khoai, cứ vai mà gọi (Small as a potato, but call by rank). In practice, age differences are commonplace, and some people may be hesitant to take advantage of their superior cousin status.

Despite this complicated system of kinship, when talking about cousins, even most Vietnamese are only concerned about anh họ, chị họ or em họ. Whether someone is "elder brother", "elder sister" or "younger sibling" depends on their relation to the speaker's parent's: for example, if the addressee is the younger brother of the speaker's mother's, his children are also always the speaker's "younger siblings" regardless of the ages of those cousins. If the speaker is married, they also inherit their spouse's cousinship, which means they will become an "older brother" or "older sister" regardless of their "younger sibling" cousins' ages.

Outside of actual kinship, kinship terms are used depending on age differences, in informal contexts, or in a friendly way toward children. When addressing a stranger, the speaker may have to consider whether this person is a bit or a lot older or younger than themself or their parents. This could be done by asking and knowing their age, or simply through guesswork. If the speaker is rather young and talking to a very old person, the speaker generally defaults to ông or bà for the addressee and cháu or con for themself. In formal contexts, however, only a few terms can be used based on how young or old the stranger appears: anh (young or middle-aged men), chị or cô (young or middle-aged women), ông (old men) and bà (old women); the reciprocal term would be the true pronoun tôi. For rather young people in their early twenties, the non-kinship term bạn ("friend") is also a recognized usage.

Singular kinship terms can be pluralized using the plural marker các, as in các anh. When speaking to an audience in a formal context, kinship terms are often strung together to cover common individual relationships: các anh chị em refers to an audience of roughly the same age, while các ông bà anh chị em, sometimes abbreviated ÔBACE, refers to an audience of all ages.

In Vietnamese, virtually any noun used for a person can be used as a pronoun. These terms usually have only one grammatical person meaning and unlike kinship terms, do not serve multiple roles. Words such as "doctor", "teacher", "owner", etc. can be used as a second-person personal pronoun when needed. When referring to themselves, Vietnamese speakers, like speakers of Chinese, Japanese, and Korean languages, tend to deprecate their position while elevating the audience. While many of these terms are obsolete, some remain in widespread usage. The most prominent is tôi, literally meaning "servant". It is used as a fairly neutral term for "I" (neither very friendly, nor very formal). Tớ, also meaning "servant", is also popular among young people to refer to themselves with close friends (used in conjunction with cậu for "lad").

Pronouns that elevate the audience still in use include quý khách (valued customer), quý vị (esteemed guests). Bạn (friend) is also popular among young people as a way of addressing each other.

Vietnamese speakers also refer to themselves and others by name, eliminating the need for personal pronouns altogether. For example:

An: Bình đang làm gì vậy?

Bình: Bình đang gọi Chính. An có biết Chính ở đâu không?

An: Không, An không biết Chính ở đâu hết.

Directly translated into English, the conversation would run thus:

An: What is Bình doing?

Bình: Bình is calling Chính. Does An know where Chính is?

An: No, An doesn't know where Chính is.

A normal translation of the conversation into English would be:

An: What are you doing?

Bình: I'm calling Chính. Do you know where he is?

An: No, I don't know where he is.

While always referring to oneself or the audience by name would be considered strange in English, in Vietnamese it is considered friendly and slightly respectful, especially between acquaintances of different genders who are not very close (as to use even more familiar terms such as tao, mày), or between young girls. Referring to oneself by name is also the preferred way used by music artists, or even actors, models, etc. However, in a kinship context, people with a lower rank cannot address their superiors by name.

With the abolishment of the monarchy, some pronouns, such as the royal we trẫm and others related to royalty, have fallen out of use and are no longer applicable. Archaic pronouns include:

• trẫm (朕) – used by the monarch to refer to themself, adopted like the Japanese chin from its use by the Chinese emperors following the example of Shi Huangdi
• khanh (卿) – used by the monarch to address a favored subject
• bệ hạ (陛下) – used by subjects when addressing the monarch; compare English "your majesty"
• thị (氏) – she

With the exception of tôi, pronouns typically go hand-in-hand with another: when one is used to refer to the speaker, the other must be used to refer to the audience.
