Jiuquan is a prefecture-level city in the westernmost part of Gansu province, People's Republic of China. The entire "prefecture-level city" (that is, a multi-county administrative unit - an equivalent to the traditional Chinese prefecture) stretches for more than 600 km (370 mi) from east to west, occupying 191,342 km2 (73,878 sq mi); 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. It was an active military garrison during the Later Han Dynasty.

It is known in popular legend as the place where rhubarb was first grown and is also the town where the Portuguese Jesuit missionary and explorer Bento de Gois (1562-1607) was robbed and died destitute.
