Ishidoriya (石鳥谷町, Ishidoriya-chō) was a town located in Hienuki District, Iwate Prefecture, Japan.

The village of Kōchi (好地村) was created on April 1, 1889 with the establishment of the municipalities system.

The village was raised to town status on April 1, 1928 and renamed Ishidoriya at that time.

On January 1, 2006, Ishidoriya, along with the town of Ōhasama (from Hienuki District), and the town of Tōwa (from Waga District), was merged into the expanded city of Hanamaki,[1] and no longer exists as an independent municipality.

Ishidoriya had a sister city relationship with Rutland, Vermont.
