Isan-seowon (이산서원) (伊山書院) is a Confucian academy located in Isan-ni, Isan-myeon, Yeongju-shi, Gyeongsangbuk-do. It was built by An Sang in 1558, during the reign of King Munjeong - the first seowon in what is now Yeongju-shi. It received the official approval of the government in 1572. Several of the original buildings no longer remain.
