The Hangzhou–Fuzhou–Shenzhen railway, also called the Hangshen railway ({{zh|s=杭福深客运专线}}, formerly {{lang|zh-hans|东南沿海快速通道}} or {{lang|zh-hans|东南沿海铁路}}) is the dual-track, electrified, high-speed rail lines (HSR) in service along the southeastern coast of China, linking the Yangtze River Delta on the East China Sea and Pearl River Delta on the South China Sea. It is one of the eight arterial high-speed rail corridors of the national 4+4 high-speed rail grid.{{cite web |date=2008-01-06 |script-title=zh:东南沿海快速通道厦门至深圳铁路广东段开工建设 |url=http://finance.sina.com.cn/roll/20080106/18251909843.shtml |publisher=Sina Finance |language=zh-hans}} Major cities along the route include Hangzhou, Ningbo, Taizhou and Wenzhou in Zhejiang; Fuzhou, Quanzhou, Xiamen and Zhangzhou in Fujian; and Chaozhou, Shantou, Shanwei, Huizhou and Shenzhen in Guangdong. An additional bridge will be built across Hangzhou Bay for high-speed rail, which would provide a direct link between Shanghai and Ningbo.{{cite web |title=Railway Bridge to Cross Hangzhou Bay |url=http://business.highbeam.com/436093/article-1G1-187600522/railway-bridge-cross-hangzhou-bay |url-status=dead |archive-url=https://web.archive.org/web/20120809000030/http://business.highbeam.com/436093/article-1G1-187600522/railway-bridge-cross-hangzhou-bay |archive-date=2012-08-09}}

The Southeast Coast HSR Corridor is approximately {{convert|1,745|km|mi|abbr=on}} in length, and crosses three coastal provinces, Zhejiang, Fujian and Guangdong. The southeast coast is the only region of high-speed rail construction where no previous conventional railroads existed. Hence, the high-speed rail lines built on the southeast coast will, for the most part are designed to carry both passenger and freight traffic, and will not be passenger-dedicated lines that comprise most of the other HSR corridors in China.

The line was later folded into the Coastal corridor as part of the reorganization into the national 8+8 high-speed rail grid plan. A number of sections, particularly in the southeast coast in Fujian and Guangdong Provinces, are now being superseded by a newly constructed roughly parallel 350kph rated fully passenger-dedicated lines.
