The Iwaki clan (Japanese: 岩城氏, Hepburn: Iwaki shi) was a Japanese samurai clan that claimed descent from the Hitachi-Heishi, a cadet branch of the Taira clan. However, this connection is tenuous and not backed by documentary evidence, suggesting that the Iwaki were instead descendants from the local Kuni no miyatsuko, and adopted the legend of Taira descent for greater prestige.
