Assamese grammar (Assamese: অসমীয়া ব্যাকৰণ Oxömia byakoron) is the study of the morphology and syntax of Assamese, an Indo-European language spoken in Northeast India, primarily in the state of Assam. It has long served as a lingua franca in parts of Northeast India. Although Assamese is typically written in the Assamese script, a romanization is also used here to suggest the pronunciation. Since there are many varieties of Assamese, the standard variety is used here.

The Assamese language has the following characteristic morphological features:

Assamese personal pronouns are somewhat similar to English pronouns, having different words for first, second, and third person, and also for singular and plural (unlike for verbs, below). However, Assamese has two different third-person pronouns for proximity. The first, called proximal, are used for someone who is present in the discussion, and the second, called distal, are for those who are nearby or at a distance but not present in the discussion. Gendered pronouns are present only in third person non-honorific. Additionally, each of the second- and third-person pronouns have different forms for the familiar and polite forms; the second person also has a "very familiar" form (sometimes called "despective"). It may be noted that the "very familiar" form is used when addressing particularly close friends or family as well as for addressing subordinates, or in abusive language.

In the following tables, the abbreviations used are as follows:

m. = masculine,

f. = feminine,

ng. = no specific gender,
