The Dharmaguptaka (Sanskrit: धर्मगुप्तक; traditional Chinese: 法藏部; pinyin: fǎzáng-bù) are one of the eighteen or twenty early Buddhist schools, depending on one's source. They are said to have originated from another sect, the Mahīśāsakas. The Dharmaguptakas had a prominent role in early Central Asian and Chinese Buddhism, and their monastic rules for bhikṣus and bhikṣuṇīs are still in effect in some East Asian countries to this day, including China, Vietnam, Korea, and Taiwan. They are one of three surviving vinaya lineages, along with the Mūlasarvāstivāda and Theravāda.
