The Miki Line (三木線, Miki-sen) was a Japanese railway line in Hyōgo Prefecture, between Yakujin Station in Kakogawa and Miki Station in Miki.

The line linked Miki and the West Japan Railway Company Kakogawa Line at Yakujin station.

[2] The majority of commuters used Kobe Electric Railway's (Shintetsu) Ao Line to get to Kobe instead of the Miki–Kakogawa Line route.

As a result, Miki Railway had been unable to justify continued financial support from the city.

On March 1, 2007, the Miki City Council officially decided to abandon the line with the company agreeing on April 26, 2007.
