The Uyghur Doppa Cultural Festival, observed annually on 5 May, celebrates the culture and history of the Uyghurs, a Turkic people originating from Xinjiang, China (historically known as East Turkestan). It is also known as Uyghur Doppa Day or just Doppa Day.
The festival was created by Uyghur activist Tahir Imin in 2009 and celebrated for the first time that year, in Imin's home city of Ürümqi. Celebrations were broadcast nationally by Chinese state television and shared by Uyghur groups abroad, popularizing it among Uyghurs in China and the Uyghur diaspora. However, since the start of the Chinese authorities' crackdown on Uyghur cultural activities in 2014, the festival is no longer observed in China.
