The Tsushima Line (津島線, Tsushima-sen) is an 11.8 km (7.33 mi) Japanese railway line which connects Sukaguchi Station in Kiyosu, Aichi with Tsushima Station in Tsushima, Aichi. It is owned and operated by the private railway operator Nagoya Railroad (Meitetsu). Manaca is accepted at all stations.

The line opened as dual track interurban operated by the Nagoya Electric Railway which is the predecessor of the Nagoya Railway. It is a commuting route to Tsushima City along the Tsushima Road. Due to the line running through low lying wetland areas, it has been damaged many times by typhoons and sudden downpours.

There are only a few trains that strictly run confined to the Tsushima line. Most trains provide through service into the Meitetsu Bisai Line bound for Saya Station and more than half the trains through service into the Nagoya Main Line.

In addition, since the regular train of Gifu direction is required to depart from the station in the Nagoya Main Line, Biwajima Branch Point of the Nagoya Main Line-each station stop between the required mouth is still the Tsushima Line direct train is responsible.
