Pulaar (in Latin: pulaar, in Ajami: ݒُلَارْ‎), often referred to as Pulaar du Nord,^{[citation needed]} is a dialect of the Fula language spoken primarily as a first language by the Fula and Toucouleur peoples in the Senegal River valley area traditionally known as Futa Tooro and further south and east. Pulaar speakers, known as Haalpulaar'en live in Senegal, Mauritania, the Gambia, and western Mali. The two main speakers of Pulaar are the Toucouleur people and the Fulɓe (also known as Fulani or Peul). Fula, considered as a single language, is the second most spoken local language in Senegal, being a first language for around 22% of the population. This correlates with 23.7% of the country in which Fulbe is the population's ethnicity. Pulaar is one of the national languages of Senegal alongside 13 others. It was admitted as an official language of Senegal by Presidential decree in 1971. There are around 28 known dialects of Fula, most of which are mutually intelligible with each other. The Fula dialects, as well as other West African languages, are usually referenced under the umbrella term ‘Fula’. Pulaar as a language, however, is not usually referenced as ‘Fula’.

According to Ethnologue there are several dialectal varieties, but all are mutually intelligible.

Pulaar is not to be confused with Pular, another variety of Fula spoken in Guinea (including the Fouta Djallon region). The Pulaar and Pular varieties of Fula are to some extent mutually intelligible.

Pulaar is currently written in primarily in the Latin script. Historically, for centuries, Pulaar has a literary tradition based on the Arabic script, an orthographic tradition now known as "Ajami". More recently, Adlam script for Pulaar has been gaining ground as well (see Fula alphabets).

The word Pulaar translates to 'the language of the Fulɓe' as the stem /pul/ is the singular form of Fulɓe and the suffix /-aar/ means language. The language is believed to have formed in Fuuta Tooro when the ancestors of the Toucouleur people began speaking the language of the Fulɓe. It is then believed that the term Haalpulaar'en (which means 'speakers of the language of Pulaar') was created to apply to non-Fulɓe speakers of Fulɓe, of which the Toucouleur people are the largest demographic.

The negative accomplished verb form ends in -aani. (This is slightly different from Maasina Fulfulde and Pular.)

Pulaar contains 21 noun classes. These noun classes can commonly be observed by looking at the suffix of a noun. For example, a noun that is the result of a loan word will typically end in -o (however, human singular nouns such as debbo (meaning woman) also end in -o). The class of the noun will often refer to the actual content of the noun. For example, the ɗam noun class is applied to nouns that describe a liquid. The table below shows the noun classes in Pulaar and what the class indicates the content of the noun to be:

The Pulaar counting system is base five (a quinary-decimal system) which is similar to the surrounding Niger-Congo languages. The number 7, for example, uses the prefix of joy (5) and the suffix ɗiɗi (2) becoming jeeɗiɗi (5+2). Other languages that use this system in West Africa include Pular, Wolof, Sereer-Sine and East Limba. These quinary-decimal counting languages can be found in the west African regions of Sierra Leone, Guinea and Gambia. Pulaar and Pular possess almost identical words for numbers, in which every number from 1 to 10 share the exact same name except for 5 (joy for Pulaar and jowi for Pular).
