TheTōkyū Tamagawa Line (東急多摩川線,Tōkyū Tamagawa-sen) is a commuter railway line in Japan owned by private railway operatorTokyu Corporation. It runs betweenTamagawa andKamata in southwestTokyo, entirely withinŌta ward. The operator's name, Tōkyū, is included in the formal name of this line.

It was formed in 2000 from the western portion of the Tōkyū Mekama Line, which was then rerouted west of Tamagawa (former Tamagawa-en) station and renamed theMeguro Line.

This line should not be confused with theTokyu Shin-Tamagawa Line (a section of track fromShibuya toFutako-tamagawa, (which has since been absorbed into theTokyu Den-en-Toshi Line), or the Tamagawa Linetramway which preceded that (of which one of its branches now forms theSetagaya Line).

All stations are located inOta.

All the rolling stock is shared withTokyu Ikegami Line.

The Tokyu Tamagawa Line was formed on 6 August 2000 with the splitting of the former Tokyu Mekama Line.^[1]Wanmandriver-only operation also commenced on the line from this date.^[1]

Plans exist to extend the line eastward by approximately 800 m from the southern terminus of the line atKamata toKeikyu Kamata Station on theKeikyu Main Line andKeikyu Airport Line, a project known as theKama-Kama Line. This would provide an interchange between the lines, improving accessibility to Tokyo'sHaneda Airport ahead of the2020 Summer Olympics.^[2] The plans did not materialize in time for the 2020 Summer Olympics. As of June 2022^[update],Ōta Ward has agreed with theTokyo Metropolitan Government to pay 70% of the project cost of¥136 billion (2021) (US$1.24 billion) while having the city government responsible for the remaining 30%.^[3]
