Yěfù Dàochuān 冶父道川 (lay surname Dí 狄; fl. 1127) was a Línjì-Yángqí school Chán master active at Yěfùshān 冶父山 in the Liǎngzhè region. He is the author of the celebrated [[KR6c0049|Jīngāng jīng zhù (X461)]], a zhuóyǔ 著語 alternating verse-and-prose commentary on the Vajracchedikā Prajñāpāramitā-sūtra — one of the most popular Chán-school commentaries on the Diamond Sūtra in the late-imperial and modern liturgical traditions. The preface dates the work to Jiànyán 1 = 1127. He is sometimes also referred to as Shí’ān Dàochuān 實菴道川.
