Turkic migration refers to the spread of Turkic tribes and Turkic languages across Eurasia and between the 6th and 11th centuries. In the 6th century, the Göktürks overthrew the Rouran Khaganate in what is now Mongolia and expanded in all directions, spreading Turkic culture throughout the Eurasian steppes. Although Göktürk empires came to an end in the 8th century, they were succeeded by numerous Turkic empires such as the Uyghur Khaganate, Kara-Khanid Khanate, Khazars, and the Cumans. Some Turks eventually settled down into a sedentary society such as the Qocho and Ganzhou Uyghurs.

Modern nations with large Turkic populations include Kyrgyzstan, Turkmenistan,
