Wakhi is an Indo-European language in the branch of Eastern Iranian language family and is intimately related to other Southeastern Iranian languages in the Pamir languages group.

Wakhi is one of several languages that belong to the Pamir language group. A reflection of this is the fact that the Wakhi people are occasionally called Pamiris. The origin of this language is Wakhan in Afghanistan and it is, according to sources, more than four thousand years old. It is spoken by the inhabitants the Wakhan Corridor of Afghanistan, parts of Gilgit–Baltistan (the former NAs) of Pakistan, Gorno-Badkhshan (mountainous-Badakhshan, in Russian) region of Tajakistan, and Xinjiang in western China. The Wakhi use the self-appellation ‘Xik’ (ethnic) and suffix it with ‘wor’/’war’ to denote their language as ‘Xik-wor’ themselves. The noun ‘Xik’ comes from ‘oxik’ (an inhabitant of ‘Ox’, for Wakhan, in Wakhi. There are other equivalents for the name Wakhi (Anglicised) or Wakhani (Arabic and Persian), Vakhantsy (Russian), Gojali/Gojo (Dingrik-wor/Shina), Guyits/Guicho (Borushaski), Wakhigi/Wakhik-war (Kivi-wor/Khow-wor) and Cert (Turki). The language belongs, as yet to be confirmed according to studies and sources, to the southern group of the Pamir languages, in the Iranian group of the Indo-European family (450) of languages, where the different Ishkashmi, Shighni/…nani and Wakhi languages are included. A very rough estimate of the population of Wakhis is 50,000 worldwide. The Wakhi live in four different countries. In the Gilgit–Baltistan region of Pakistan, the Wakhi people mainly live in Gojal, Ishkoman, Darkut and in Chitral District's Broghol. They also live in some parts of Gorno-Badakhshan in Tajikistan and Xinjiang in China.

The Wakhi people, or Khik (called Guhjali in upper Hunza), are an ethnic group originating in the Wakhan of today's Afghanistan. They also live in adjacent areas of Tajikistan and Xinjiang and in Pakistan (in Chitral District and Gojal). They speak the Wakhi language.

A very rough estimate puts the population of Wakhis at about 100,000.^{[citation needed]} The population is divided among four different countries: Afghanistan, Tajikistan, Pakistan, and Xinjiang in western China. In China and Afghanistan the Wakhi are officially recognized as "Tajiks", while in Tajikistan Wakhi are recognized by the state as Tajiks but also self-identify as Pamiris. The religion of Wakhis is Nizari Ismaili Shia Muslim, being followers of the Aga Khan.

In Pakistan, the central organization of Wakhis is the Wakhi Tajik Culture Association Pakistan (WCA), an organization that is working with the Pakistani Ministry of Culture and Tourism and Lok Virsa Pakistan. The WCA aims to preserve the Wakhi language and culture and to record its poetry and music. The WCA has arranged more than twenty programmes since 1984, including cultural shows, musical nights, large-scale musical festivals with the collaboration of Lok Virsa Pakistan, Aga Khan Cultural Service Pakistan (AKCSP), and Pakistan Television. In 2000, the WCA won a "Best Programme" organizer award in the Silk Road Festival from the President of Pakistan, Pervez Musharraf.
