The Keihin-Tōhoku Line is a railway line in Japan which connects the cities of Saitama, Kawaguchi, Tokyo, Kawasaki, and Yokohama. It is part of the East Japan Railway Company (JR East) network. The Keihin-Tōhoku Line officially follows portions of the Tōhoku Main Line and Tōkaidō Main Line. Between Ueno and Akabane stations the Keihin-Tohoku and Tohoku Main lines are physically separate and thus alternate routes.

Most Keihin-Tōhoku Line trains have a through service onto the Negishi Line between Yokohama and Ōfuna stations. As a result, the entire service between Ōmiya and Ōfuna is typically referred to as the Negishi Line on system maps and in-train station guides. Keihin-Tōhoku Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).

As of January 2010, all Keihin-Tohoku Line services are formed of E233-1000 series 10-car electrical multiple unit (EMU) trains. These were phased in from December 2007, and replaced the previous 209 series 10-car EMUs by 24 January 2010. All Keihin-Tohoku Line rolling stock is based at Urawa Depot. Yokohama Line E233-6000 series 8-car EMUs also operate on through services over the Keihin-Tohoku Line between Higashi-Kanagawa and Ofuna stations.
