Dongcheng South railway station (simplified Chinese: 东城南站; traditional Chinese: 東城南站; pinyin: Dōngchéng Nán Zhàn; Jyutping: Dungsing Naam Zaam) is a railway station in Dongcheng Subdistrict, Dongguan, Guangdong, China. It opened on December 28, 2017.

In the early stage of the intercity planning of Dongguan and Huizhou, there was an elevated station on the north side of Xiping Reservoir on Huancheng South Road called Guanchang Coach Terminal. In 2010, after the Ministry of Railways intervened in the construction of the Pearl River Delta Metropolitan Region intercity railway, the line scheme was redesigned. Finally, at the suggestion of Dongguan City and the towns and streets along the line, in order to avoid cutting the urban planning and avoid ecologically sensitive points such as Shuilian Mountain Forest Park and Tongsha Forest Park, the Dongguan urban area, Liaobu and Changping sections were changed from elevated to underground, so the station was adjusted to the underground Dongcheng South Station, and shifted northeast to the current site.

In addition, the station will provide an interchange with Dongguan Rail Transit Line 1, which has reserved a transfer passageway in the concourse.
