Brahui (Urdu: براہوی) or Brahvi (براوی) is a Dravidian language spoken by Brahui people of Pakistan and Afghanistan, and expatriate communities in Qatar, United Arab Emirates, Iraq, and Iran. It is isolated from the nearest Dravidian-speaking neighbour population by a distance of more than 1,500 kilometres (930 mi).

Brahui is spoken in the southwest region of Pakistan, as well as regions of Afghanistan and Iran which border Pakistan; however, many members of the ethnic group no longer speak Brahui. The 2005 edition of Ethnologue reports that there are some 2.2 million speakers; 90% of those live in Pakistan, mainly in the region of Balochistan.

Brahui belongs, with Kurukh (Oraon) and Malto, to the northern subfamily of the Dravidian family of languages. It has been influenced by the Iranian languages spoken in the area, especially Balochi.^{[page needed]}

Brahui language is seen as a recent migrant language to its present region. Scholars accept that Brahui could only have migrated to Balochistan from central India after 1000 AD. The absence of any older Iranian (Avestan) loanwords in Brahui supports this hypothesis. The main Iranian contributor to Brahui vocabulary, Balochi, is a Northwestern Iranian language, and moved to the area from the west only around 1000 AD. One scholar places the migration аs late as the 13th or 14th century.^{[page needed]} However, a few scholars have hypothesised that Brahui is a remnant of a formerly widespread Dravidian language family that is believed to have been reduced or replaced during the influx of Iranian/Indo-Aryan languages upon their arrival in South Asia.

The Brahui or Brohi (Brahui: براہوی) (Sindhi: بروہي ) are an ethnic group of about 2.2 million people with the majority found in Kalat, Baluchistan, Pakistan, but they are also found in smaller numbers in neighboring Afghanistan and Iran. The Brahuis are almost entirely Sunni Muslims.

The ethnonym "Brahui" is a very old term and a purely Dravidian one. The fact that other Dravidian languages only exist further south in India has led to several speculations about the origins of the Brahui. There are three hypotheses regarding the Brahui that have been proposed by academics. One theory is that the Brahui are a relic population of Dravidians, surrounded by speakers of Indo-Iranian languages, remaining from a time when Dravidian was more widespread. Another theory is that they migrated to Baluchistan from inner India during the early Muslim period of the 13th or 14th centuries. A third theory says the Brahui migrated to Balochistan from South India after 1000 AD. The absence of any older Iranian (Avestan) influence in Brahui supports this hypothesis. The main Iranian contributor to Brahui vocabulary is a northwestern Iranic language, Baluchi, and southeastern Iranic language, Pashto.
