The Longhai railway (Chinese: 陇海铁路; pinyin: Lǒnghǎi Tiělù), formerly romanized as the Lunghai railway, is a major arterial east–west railway in China. It runs from Lianyungang, Jiangsu, on the Yellow Sea to Lanzhou, Gansu, through the provinces of Jiangsu, Anhui, Henan, Shaanxi, and Gansu, covering a total length of 1,759 kilometres (1,093 mi). The line is named after Gansu, also known as Long (陇) in Chinese and Lianyungang's previous name, Haizhou.^[1] The Longhai Line is one of the busiest Chinese railways. It has dual tracks throughout and electrification was completed in 2009.

The Longhai railway was built over the course of half a century by four different governments of China: the Qing dynasty, Beiyang Government, Nationalist Government and the People's Republic.

The first section of the railway, entirely within Henan, from Kaifeng to Luoyang was built from 1905 to 1909 by a venture between the Qing dynasty and a Belgian joint-stock company backed by France and Russia.^[1] This line, known as the Bianliang–Luoyang railway, began operation on January 1, 1910.^[1]

The line was extended eastward to Xuzhou in 1916 and to Haizhou in 1925 with Dutch financing.^[1] In the west, the line was extended to Lingbao, Henan, in 1927 with Belgian financing.^[1] After the Northern Expedition, the Nanjing-based Republican government took control of construction and extended the line further west to Tongguan, Shaanxi, in 1931; Xi'an in 1934; Baoji, Shaanxi, in 1936; and Tianshui, Gansu, in 1945.^[1]

The railway was the centerpiece of Japanese operations in Henan during the Second Sino-Japanese War, with the Imperial Japanese Army repeatedly attempting to seize the railway in 1938 in the Battle of Northern and Eastern Henan^[2] and later during Operation Ichi-go.^[3]

Construction of the Tianshui to Lanzhou section, entirely within Gansu, broke ground in May 1946 but was halted by Chinese Civil War, then resumed under the People's Republic in April 1950 and was completed in July 1953.^[1] At this time, the entire Longhai railway entered into operation.^[1]

In the late 1950s through early 1960s, new railways were built from Lanzhou to the west: the Lanxin railway to Xinjiang (later connected to Kazakhstan) and the Lanqing railway to Qinghai (later extended to Tibet).

From 1956 to 1970, the section between Zhengzhou, Henan, and Baoji, Shaanxi, was upgraded to the dual-track line. During the same time, in Henan the line near Sanmenxia was re-routed due to the Sanmenxia Reservoir Project. The Zhengzhou to Shangqiu section was converted to dual-track in 1980.

The railway is a central section in the New Eurasian Land Bridge.

The Xuzhou–Lanzhou high-speed railway, a high-speed rail line, has been built parallel to the Longhai line. The Zhengzhou–Xi'an section opened in February 2010. The last section of the corridor, the Baoji–Lanzhou high-speed railway was completed on 9 July 2017.

The corridor was extended with the opening in February 2021 of the Lianyungang–Xuzhou high-speed railway, which runs parallel to the Longhai line between Xuzhou and Lianyungang.
