Zuojhen District[1][2][3][4][5] (Chinese: 左鎮區; Hanyu Pinyin: Zuǒzhèn Qū; Tongyong Pinyin: Zuǒjhèn Cyu; Pe̍h-ōe-jī: Chó-tìn-khu) is a rural district of about 4,410 residents in Tainan, Taiwan.

After the handover of Taiwan from Japan to the Republic of China in 1945, Zuojhen was organized as a rural township of Tainan County.

On 25 December 2010, Tainan County was merged with Tainan City and Zuojhen was upgraded to a district of the city.

The district consists of Guanghe, Ronghe, Zuozhen, Zhongzheng, Muguang, Neizhuang, Dengshan, Ganglin, Caoshan and Erliao Village.
