Ōtsu Station (大津駅, Ōtsu-eki) is a passenger railway station located in the city of Ōtsu, Shiga Prefecture, Japan, operated by the West Japan Railway Company (JR West).

The railway with the port station provided joint service with boats on the lake which enabled the transport of passengers and freight between the new capital, Tokyo, and the old capital, Kyoto, despite incompleteness of the railway in the Shiga Prefecture area.

The boats left each port, Ōtsu and Nagahama, 3 times a day and took about 3 hours to cross the lake.

Later in 1898 passenger service was revived on the branch, which in 1909 was named the Ōtsu Line.

In March 1913 Ōtsu Densha Kidō tramway started operation using a part of the track of the Ōtsu Line and the passenger service on the line was again discontinued.
