The Xiaoshan–Ningbo railway or Xiaoyong railway (simplified Chinese: 萧甬铁路; traditional Chinese: 蕭甬鐵路; pinyin: Xiāoyǒng tiělù), is a double-track railroad in eastern China between Hangzhou and Ningbo in Zhejiang Province.

Its name in Chinese, the Xiaoyong Line, is named after the railway's two terminal stations, Hangzhou South in Xiaoshan District of Hangzhou on the southern bank of Qiantang River, and Ningbo, whose Chinese character abbreviation is yong.

The line is 147.3 km (92 mi) long and was originally built in three parts in 1912, 1914 and 1936; rebuilt in 1959, then electrified in 2009.

Cities along route include Xiaoshan District of Hangzhou, Shaoxing, Shangyu, Yuyao and Ningbo, all in Zhejiang Province.
