Soga no Iruka (蘇我 入鹿) (died July 10, 645) was the son of Soga no Emishi, a statesman in the Asuka Period of Japan.

He was assassinated at court in a coup d'état involving Nakatomi no Kamatari and Prince Naka-no-Ōe (see: Isshi Incident), who accused him of trying to murder Prince Yamashiro, a charge which Soga no Iruka denied. Soga no Emishi also committed suicide soon after his son's death, and the main branch of the Soga clan became extinct. Prince Naka-no-Oe later ascended the throne as Emperor Tenji, and Nakatomi no Kamatari was promoted and given the name Fujiwara no Kamatari.

In 2005, the remains of a building which may have been Soga no Iruka's residence were discovered in Nara. This discovery appeared to be consistent with the description found in Nihon Shoki.^[1]
