The Ōfunato Line (大船渡線, Ōfunato-sen) is a local railway line in Iwate Prefecture, Japan, operated by the East Japan Railway Company (JR East).

The eastern section of the line was significantly damaged by the 2011 Tōhoku earthquake and tsunami on 11 March 2011.

In January 2012, services resumed on the western 62.0 km (38.5 mi) portion of the route between Ichinoseki and Kesennuma.

The eastern section between Kesennuma and Sakari remains closed, and in February 2012, JR East officially proposed that this section of the line be scrapped and the right-of-way used as a bus rapid transit (BRT) route.
