Śuddhamati 淨意菩薩 (Sanskrit Śuddhamati, “Pure-mind”) was an Indian Buddhist ācārya of uncertain dates, presumably of the late fifth or early sixth century. He is known to East Asia almost exclusively as the author of the Pratītyasamutpāda-śāstra 十二因緣論 (KR6o0055), translated into Chinese by 菩提流支 (Bodhiruci) at Luòyáng or Yè under Northern Wèi patronage. The work is doctrinally Yogācāra-Sarvāstivāda in orientation. He is sometimes identified in modern scholarship with a bhadanta in the lineage of Asaṅga and Vasubandhu, but the basis is slim. He is not the same as Wònsùck (Yuance) 圓測’s Cheng-Yuanyi 淨意 of the seventh-century Korean lineage.
