Isawa (胆沢町, Isawa-chō) was a town located in Isawa District, Iwate Prefecture, Japan.

The name of the area is derived from the ancient Isawa tribe of Emishi who had put up fierce resistance to the Yamato court and its imperial aspirations.

Isawa village proper was created on April 1, 1955 through the merger of the villages of Oyama, Natsuta and Wakayanagi.

On February 20, 2006, Isawa, was merged with the cities of Esashi and Mizusawa, the town of Maesawa, and the village of Koromogawa (both from Isawa District), was merged to create the city of Ōshū, and no longer exists as an independent municipality.
