Kishin Line (姫新線, Kishin-sen) is a railway line operated by West Japan Railway Company (JR West) between Himeji, Hyōgo and Niimi, Okayama, Japan.

Journey times were reduced from spring 2010 after the entire fleet of new trains had been delivered.

[1] The first section of the line opened was from Tsuyama to the north in 1923, and the line was progressively extended until it reached Niimi in 1929.

The section from Himeji opened in stages from 1930, and the line was completed in 1936.

CTC signalling was commissioned in 1986, and freight services ceased the following year.
