Line S9 is a north–south suburban metro line in the Nanjing Metro (Chinese: 南京地铁S9号线; pinyin: Nánjīng Dìtiě S-Jiǔ Hào Xiàn) system, which opened on December 30, 2017. It connects to Line S1 at Xiangyulunan and crosses Shijiu Lake on a 12 km (7.5 mi) long bridge between Mingjue and Tuanjiewei.

Line S9 also serves as the second stage of the Nanjing–Gaochun Intercity Railway, with Line S1 serving as the first stage. In June 2019 a few express trains started operating during rush hour, running non-stop between Xiangyulunan and Gaochun.
