The Meitetsu Bisai Line (名鉄尾西線, Meitetsu Bisai-sen) is a 30.9 km (19.2 mi) Japanese railway line which connects Yatomi Station in Yatomi, Aichi with Tamanoi Station in Ichinomiya, Aichi.

The Yatomi to Tsushima section was opened in 1898 by the Bisai Railway, and was extended to Ichinomiya in 1900.

The Kiso-Minato to Morikami section was electrified at 600 V DC in 1922, and extended to Yatomi the following year.

In 1948, the voltage on the Yatomi to Tsushima section was raised to 1,500 V DC, with this increase extended to the rest of the line in 1952.

The Kiso-Minato to Tamanoi section closed in 1959.
