The Tsurumi Line (Japanese: 鶴見線, romanized: Tsurumi-sen) is a group of 3 railway lines operated by East Japan Railway Company (JR East) in Kanagawa Prefecture, Japan. Originally built to service the port and adjacent industrial area, the lines provide passenger services (especially for local workers) along a line between Tsurumi Station in Tsurumi-ku, Yokohama and Ōgimachi Station in Kawasaki-ku, Kawasaki, and 2 short branches with a total length of track to 9.7 km (6.0 mi). The gauge is 1,067 mm (3 ft 6 in), two sections of the line have double track and the line is electrified at 1,500 V DC.

Japan Freight Railway Company (JR Freight) operates on three segments of the line, often to carry petroleum and other chemicals from the numerous refineries and factories in the area. The line is also used to carry jet fuel from the US Navy fuel depot near Anzen Station through the Musashino Line to Yokota Air Base in west Tokyo.

The Tsurumi Port Railway (鶴見臨港鉄道, Tsurumi Rinkō Tetsudō) opened the Bentembashi to Hama-Kawasaki line, including the branch to Okawa in 1926, and extended the mainline to Ogimachi in 1928. In 1930, the Tsurumi to Bentembashi section opened, the lines were electrified at 600 V DC, and passenger services commenced on both lines.^{[citation needed]} The Asano to Shin-Shibaura section opened as a freight-only line in 1932, and was extended to Umi-Shibaura in 1940, with passenger services commencing upon the opening of the extension.^{[citation needed]}

The company was nationalised in 1943, and in 1948 the voltage was increased to 1,500 V DC.^{[citation needed]}

On 20 August 2016, station numbering was introduced with Tsurumi line stations being assigned station numbers between JI01 and JI10.^[6][7] Station numbers were also introduced to the Umi-Shibaura branch (station numbers JI51 and JI52) as well as the Ōkawa branch (station number JI61).
