The Tōkyū Setagaya Line is a light rail line in Tokyo, Japan, operated by Tokyu Corporation. It connects Sangen-Jaya to Shimo-Takaido, entirely within Setagaya, Tokyo.

Unlike other Tokyu lines that are heavy rail commuter lines, the Setagaya Line is governed under the Tramways Act of the Japanese government. Despite this, the entire line is located on its own right-of-way because it is a branch line of the former Tamagawa Line, which is not the same line as the present-day Tōkyū Tamagawa Line.
