The Kiso River (木曽川, Kiso-gawa) is a river in the Chubu region of Japan roughly 229 km (142 mi) long, flowing through the prefectures of Nagano, Gifu, Aichi, and Mie before emptying into Ise Bay a short distance away from the city of Nagoya.

The Kiso River embankment (木曽川堤, Kiso-gawa tsutsumi) was built in the Edo period and extends for a 47 kilometer between the cities of Inuyama and Yatomi to protect against flooding.

A seven-kilometer portion of this embankment between the cities of Ichinomiya and Kōnan has been designated as both a National Place of Scenic Beauty and Natural Monument since 1927.

Other portions of the Kiso River in Inuyama, and Kakamigahara, Kani, and Sakahogi in Gifu Prefecture were designated collectively as a National Place of Scenic Beauty in 1934.
