The Kawagoe Line (Japanese: 川越線, romanized: Kawagoe-sen) is a railway line in Japan operated by the East Japan Railway Company (JR East), which connects the cities of Saitama, Kawagoe, and Hidaka in Saitama Prefecture.

On the western section between Kawagoe and Komagawa, about half of all trains travel through to/from Hachiōji via the Hachikō Line.

The tracks were doubled between Ōmiya to Nisshin, and a new EMU depot was opened close to Minami-Furuya Station.
