Midong District (Chinese: 米东区; pinyin: Mǐdōng Qū; Uyghur: مىچۈەن-كۆكتاغ رايونى, romanized: Michüen-Köktagh Rayoni, Miqüen-Kɵktaƣ Rayoni, Мичүән-Көктағ Райони) is one of 7 urban districts of the prefecture-level city of Ürümqi, the capital of Xinjiang Uygur Autonomous Region, Northwest China.

[2] Midong District was formed in 2007 by merging the former "Dongshan District" (Chinese: 东山区; pinyin: Dōngshān Qū; Uyghur: دۇڭسەن رايونى, romanized: Dungsen Rayoni, Dungsən Rayoni, Дуңсән Раүони) of Ürümqi (244 km2 or 94 sq mi, population of 100,000, as per the 2002 Census) with the "Miquan City" (Chinese: 米泉市; pinyin: Mǐquán Shì; Uyghur: مىچۈەن شەھىرى, romanized: Michüen shehiri; formerly part of Changji Hui Autonomous Prefecture).

The natural water sources in the Ürümqi area mostly consist of streams that flow from the snow-capped Tian Shan mountains south of the city.

Since Midong District is located north and therefore downstream, of the main urban area, the water supply problems there are particularly acute.

Its main terminal is the so-called "Reservoir 500", constructed at the border of Midong District and Fukang County-level City (44°12′00″N 87°49′00″E / 44.20000°N 87.81667°E / 44.20000; 87.81667).
