The Tokushima Line (徳島線, Tokushima-sen) is a railway line in Tokushima Prefecture, Japan, owned and operated by Shikoku Railway Company (JR Shikoku).

In addition to linking Tokushima and Kōchi prefectures, the line's eastern half serves the city of Tokushima as a commuter line.

This is to allow for more efficient connecting service to the Dosan Line at Tsukuda.

In the March 2009 timetable revision, a single inbound Muroto limited express was established, providing through service to Kaifu on the Mugi Line.

The Tokushima Line serves as a bypass route between Tokushima and Kōchi; in the past, the Asa and Yoshinogawa express and some Tsurugisan limited express services connected the two cities (now passengers must change at Awa-Ikeda to the Nanpū limited express).
