Iwa Jinja (伊和神社) is a Shinto shrine in the Ichinomiya neighborhood of the city of Shisō in Hyōgo Prefecture, Japan.

Although destroyed periodically by fire, it has been rebuilt with the support of the Imperial Court, the Akamatsu clan and various feudal lords.

After the Meiji Restoration, it was listed as a National Shrine, 2nd rank (国幣中社, Kokuhei Chusha) in 1871.

The shrine is in Ichinomiya Town, Shisō County, Hyōgo Prefecture.

[5] Every twenty years, the Three Mountains Rite takes place at Iwa Shrine.
