"Wanzhou" literally means "myriad-prefecture", where "a myriad rivers converge and a myriad traders gather" (万川毕汇、万商云集). Due to the construction of the Three Gorges Dam, 47% of Wanzhou's old urban area will be underwater by the time the reservoir is filled. Buildings in the submerged area have been torn down and new ones rebuilt on higher ground.
The district was part of Wanxian Prefecture, then the prefectural Wanxian City. It was renamed to Wanzhou in late 1990s.
It was part of Quren District of Ba Prefecture (巴郡朐忍县) in the Qin Dynasty. It became Yangqu District (羊渠县) in 216 (the Eastern Han Dynasty). In 230 (the Shu-Han Kingdom), it was renamed to Nanpu (南浦县); in 553 (the Western Wei Dynasty), to Yuquan (鱼泉县); in 557 (Northern Zhou Dynasty), to Anxiang (安乡县); in 584, to Wanchuan (万川县); and in 598 (Sui Dynasty), to Nanchang again.
It continued to be renamed and administrated with slight differences. In the 19th century, it was known in English as Wanhsien and Wan County In 1935, it became Wanxian Zhuanqu (万县专区). On December 12, 1992, the State Council abolished Wanxian Prefecture and its subordinate Wanxian City and created the prefecture-level Wanxian City, which administered the districts of Longbao (龙宝区), Tiancheng (天城区), Wuqiao (五桥区) and the counties of Kai, Zhong, Liangping, Yunyang, Fengjie, Wushan, Wuxi, and Chengkou.
The entire Wanxian City was merged into Chongqing on December 20, 1997. The merge necessitated the abolishment of Wanxian City and creation of Wanxian District and Wanxian Migration Development Area (移民开发区). Wanxian City's three districts were converted to administrative committees (管理委员会, abbreviated 管委会) of Wanxian District. The migration development area included the counties formerly in Wanxian City, except Liangping and Chengkou, which were administered by Chongqing directly.
On May 22, 1998, the State Council approved that the two areas named Wanxian were both renamed to Wanzhou. The migration development area later dissolved and its counties were directly controlled by Chongqing. On July 19, 2000, the district's administrative committees were changed to migration development areas.
