Alian District is a rural district in Kaohsiung, Taiwan.
After the handover of Taiwan from Japan to the Republic of China in 1945, Alian was organized as a rural township of Kaohsiung County. On December 25, 2010, Kaohsiung County was merged with Kaohsiung City and Alian was upgraded to a district of the city.
The district is located at the northeast of the Kaohsiung Plain on the north end of western Kaohsiung City, between the Erren River and the Agongdian River.[2]
The district consists of Shian, Zhonglu, Fengshan, Ganghou, Gangshan, Alian, Qinglian, Helian, Jingqi, Fuan, Yuku and Nanlian Village.[3]
The district is connected to Tainan's Xinhua District through Provincial Highway 39, to Luzhu and Tianliao through Provincial Highway 28, and to Guanmiao, Tainan and Gangshan through Provincial Highway 19A.
