The Kakogawa Line (加古川線, Kakogawa-sen) is a railway line in Hyōgo Prefecture, Japan, operated by West Japan Railway Company (JR West), which connects the cities of Kakogawa and Tamba.

The Banshu Railway opened the Kakogawa - Nishiwakishi section in 1913, and extended the line to Tanikawa in 1924.

Freight services ceased in 1986, and CTC signalling was commissioned on the entire line in 2004.

Former branches of the Kakogawa Line included the Takasago Line (connected at Kakogawa Station), the Miki Line (connected at Yakujin Station) and the Kajiya Line (connected at Nomura Station, i.e. present-day Nishiwakishi Station).
