Khorasani Turkic or Khorasani Turkish is an Oghuz Turkic language spoken in the North Khorasan Province and the Razavi Khorasan Province in Iran. Nearly all Khorasani Turkic speakers are also bilingual in Persian.^[1]

Khorasani Turkic is spoken in the Iranian provinces of North Khorasan near Bojnord and Razavi Khorasan near Sabzevar, Quchan. The Oghuz dialect spoken in Western Uzbekistan is sometimes considered a dialect of Khorasani Turkic.^{[citation needed]}

Khorasani Turkic is split into North, South and West dialects. The northern dialect is spoken in North Khorasan near Quchan; the southern in Soltanabad, near Sabzevar; the western, around Bojnord.

Khorasani Turkic belongs to the Oghuz group of Turkic languages, which also includes Turkish, Azerbaijani, Gagauz, Balkan Gagauz, Qashqai, Turkmen and Salar.

Khorasani Turkic was first classified as a separate dialect by Iranian Azerbaijani linguist Javad Heyat in the book Tārikh-e zabān o lahcayā-ye Türki (History of the Turkic dialects).^[3] According to some linguists, it should be considered intermediate linguistically between Azerbaijani and Turkmen, although it is sufficiently distinct not to be considered a dialect of either.^[3] It is considered by Turkic scholars to be most closely related to the other Oghuz varieties spoken in Iran, and a close relationship with Turkmen has been disputed on the basis of the comparisons of the core set of agglutinating morphemes.^[4]

Doerfer and Hesche classify Khorasani Turkic into different branches within the Oghuz languages.^[5]

According to Robert Lindsay, Khorasani Turkic has four branches:^[6]

Glottolog lists seven distinct dialects:^[7]
