Akō Line (赤穂線, Akō-sen) is a railway line owned by West Japan Railway Company (JR West) between Aioi, Hyōgo to Okayama, Okayama in Japan. A loop line off the Sanyō Main Line, the Akō Line commences at Aioi, is situated south of the main line approximately paralleling the Seto Inland Sea, and rejoins the main line at Higashi-Okayama.

The entire 57.4-kilometre (35.7 mi) line is single track. Only one train runs the entire length of the line, with service divided at Banshū-Akō, and no trains terminate at either of the official terminals. Trains from the east continue from Himeji on the Sanyō Main Line and terminate at Akō, while westbound services originating from Akō continue past Higashi-Okayama and continue on the Sanyō Main Line to Okayama and beyond. "Rapid" and "Special Rapid" trains from Kyoto and beyond make local stops between Aioi and Banshū-Akō, and the segment of the line is part of JR West's Kinki region Urban Network.

Stations

The line is split into two sections at Banshū-Akō Station, where passengers would have to interchange for train services to/from the Keihanshin region and the Okayama region.
