The Takasago Line (高砂線 Takasago-sen?) was an 8.0-kilometer long railway line of Japanese National Railways between Kakogawa and Takasago all within Hyōgo Prefecture, Japan. This line existed between 1913 and 1984.
The Banshū Railway (播州鉄道 Banshū Tetsudō?) opened the line between Kakogawachō and Takasagoguchi (2.9 miles) on December 1, 1913. The line was extended 1.9 miles to Takasagoura on September 25, 1914 completing the 4.8-mile line. The 0.9-mile section between Takasago and Takasagoura ceased passenger service in 1921.
The railway was acquired by the Bantan Railway (播丹鉄道 Bantan Tetsudō?) in 1923 and nationalized in 1943 together with other Bantan Railway lines, i.e. the Kakogawa Line, the Kajiya Line, the Miki Line and the Hōjō Line. At the time of nationalization, Kakogawachō Station was merged to JGR Kakogawa Station and Takasagoura Station was renamed Takasagokō Station.
