The Keihin-Tōhoku Line (京浜東北線 Keihin-tōhoku-sen?), 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 line's name is derived from the characters for Tokyo (東京?), Yokohama (横浜?) and the Tōhoku Main Line (東北本線?). 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.
All Keihin-Tōhoku Line trains have 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 Keihin-Tōhoku—Negishi Line (京浜東北線・根岸線?) on system maps and in-train station guides. Keihin-Tōhoku Line—Negishi Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).
Trains run every 2–3 minutes at peak hours, every 5 minutes during the daytime, and less frequently the rest of the time. In most instances, these trains are classified as "Local" (各駅停車 Kakueki-Teisha?), stopping at all stations en route. However, during the daytime, trains are classified as "Rapid" (快速 kaisoku?). These rapid trains skip some stations in central Tokyo, where it runs parallel to the Yamanote Line.
- Local trains stop at all stations. Rapid trains stop at stations marked "●" and "■". (Stations marked "■" allow cross-platform transfers to the Yamanote Line.)

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 205 series and E233-6000 series 8-car EMUs also operate on through services over the Keihin-Tohoku Line between Higashi-Kanagawa and Ofuna stations.

The Keihin Line (京浜線?) opened in 1914 as an electrified passenger line connecting Tokyo Station with Takashimacho Station in Yokohama. (The latter station was renamed Yokohama Station in 1915, when the former Yokohama Station was renamed Sakuragicho Station). The Keihin Line service was extended north through the Tōhoku Main Line to Akabane Station in 1928 and to Ōmiya Station in 1932: this service was initially called the Tōhoku-Keihin Line in announcements.
The Keihin Line initially had third-class and second-class cars, analogous to today's ordinary cars and Green Cars respectively. Second-class service ended in 1938 in order to accommodate special military cars during World War II. The military seating was converted to seating for women and children after the war, and back to ordinary seating in 1973 amid overcrowding concerns: second-class service was briefly restored in the 1950s but abandoned shortly thereafter.
In 1956, the Keihin-Tohoku Line was physically separated from the Yamanote Line between Tamachi and Tabata, allowing more frequent service. Through service with the Negishi Line began in 1964. The frequency increased again in 1968 when the Tohoku Main Line moved to separate tracks. Limited-stop "Rapid" services were introduced in 1988 to further ease congestion along the Yamanote Line corridor.
At around 01:11 in the morning of 23 February 2014, an empty stock train operating from Sakuragicho to Kamata hit a track maintenance vehicle on the track close to Kawasaki Station. The first two cars of the 10-car E233 series train derailed, with the first car ending up on its side. The train was carrying no passengers, and the driver and conductor escaped with minor injuries.
