Gao'an (Chinese: 高安; pinyin: Gāo'ān) is a county-level city in the northwest-central part of Jiangxi province, China. It is under the jurisdiction of the prefecture-level city of Yichun, and is located about 35 kilometers west from Nanchang, the provincial capital. It covers an area of 2439.33 square kilometers and has an estimated population of 1 million people. In 1993, it became a city comprising 20 smaller towns. It is well known for calligraphy and thriving ceramics industry.^{[citation needed]}

Gao'an County, was founded in 201 B.C. and was formerly named Jiancheng (建成). Its administrative divisions today include Gao'an, Shanggao, Yifeng, Wangzai, and a part of Zhangshu.^{[citation needed]}

In 4 A.D., Jiancheng County was renamed Duoju County, and then in 25 A.D its name was reverted to Jiancheng. From 184 to 189, a part of Jiancheng was transferred to Shangcai County (now Shanggao County). During the late Eastern Han dynasty (4 A.D.), and again during the Three Kingdoms period, Jiancheng County belonged to Sunwu power.^{[citation needed]}

During the Jin and Southern dynasties, Jiancheng County belonged to Yuzhang Shire. In 589, the Sui dynasty united the country, abolished Shangcai, merged Yangle, and restored Yicheng to Jiancheng. During this period, Jiancheng County was changed into Hongzhou.^{[citation needed]}

In 622, in order to avoid the name to be same with the prince Li Jiancheng, the county's name was changed to Gao'an. According to the Taiping Huanyuji (《太平寰宇记》), "the terrain is high but flat, so name it Gao'an" (“地形似高而安，故名”). (In Chinese Gao means high and An means flat.) In 624, Gao'an became part of Yunzhou.^{[citation needed]}

During the Five Dynasties and Ten States period, Gao'an belonged to the Wu power at first but was administrated by the Nantang power later. In 981, a part of Gao'an and Shanggao was marked to be Xinchang County (now Yifeng County). ^{[citation needed]}

In 1932, the whole province was divided into 13 administrative regions, and Gao'an was part of the first one. In 1935, there were eight administrative regions, and Gao'an became part of the second region. In 1942, the province was adjusted to have nine administrative regions, and Gao'an was once again part of the first. On July 10, 1949, Gao'an was liberated. Four days later, the Gao'an government was established, and belonged to Nanchang, Jiangxi province. Later on, Gao'an belonged to Yichun.^{[citation needed]}

On December 8, 1993, the state council approved Gao'an to be a prefecture-level city governed by Yichun.^{[citation needed]}
