The official languages of Afghanistan are Pashto and Dari (Farsi), both of which are Iranic languages.

Pashto is widely spoken by the Pashtun people, who mainly reside towards the south of Afghanistan on the Pakistani-Afghan border. A few Turkic languages, like Uzbek and Turkmen, are spoken near regions closer to Uzbekistan and Turkmenistan.
