Jiuquan (酒泉 | Jiǔquán Shì) is a "prefecture-level city" in the westernmost part of the Gansu province in China.
The entire "prefecture-level city" (that is, a multi-county administrative unit - an equivalent to the traditional Chinese prefecture) stretches for more than 500 km from east to west, occupying 191,342 km²; its population as of 2002 was 962,000.
The city's name came from legendary tale of the young Han general Huo Qubing, who poured a jar of precious wine into a local creek in order to share the taste with his troops, in celebration of their crushing victory against Xiongnu forces. The creek was later named Jiu Quan ("Wine Spring"), which became the name of the Han prefecture established there.
