The Tokyu Tamagawa Line (東急多摩川線, Tōkyū Tamagawa-sen^?) is a commuter railway line in Japan owned by private railway operator Tokyu Corporation. It runs between Tamagawa and Kamata in southwest Tokyo, entirely within Ōta ward. The operator's name, Tokyu, is included in the formal name of this line.

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

The current Tokyu Tamagawa line should not be confused with the Tokyu Shin-Tamagawa line (a section of track from Shibuya to Futako-Tamagawa(en), since absorbed into the Tokyu Den-en-Toshi Line or the Tamagawa-line tramway which preceded that.

The Tokyu Tamagawa Line was formed on 6 August 2000 with the splitting of the former Tokyu Mekama Line.Wanman driver-only operation also commenced on the line from this date.

Plans exist to extend the line eastward by approximately 800 m from the southern terminus of the line at Kamata to Keikyu Kamata Station on the Keikyu Main Line and Keikyu Airport Line. This would provide an interchange between the lines, improving accessibility to Tokyo's Haneda Airport ahead of the 2020 Summer Olympics.
