Yuán-kāng 元康 (fl. mid-7th c.), Tang-period Chinese Buddhist monk of the Sān-lùn 三論 lineage, principal Tang-period commentator on Sēng-zhào’s Zhào-lùn (KR6m0038 T1858). The biographical record is fragmentary: Yuán-kāng is named in the colophon of KR6m0039 Zhào-lùn shū T1859 simply as “the śramaṇa Shì Yuán-kāng” 釋元康, without further biographical detail. The Sòng gāosēng zhuàn 宋高僧傳 (T2061, juan 4) supplies a brief notice locating him at the Cháng’ān imperial monastic establishment in the early 650s, where he was attached to the Yīng-tiān-sì 應天寺 and later moved to the Tōng-quán-sì 通泉寺 in the Yán-ān 延安 region; he was active as a lecturer and commentator on the Sān-lùn texts.
His principal work is the KR6m0039 Zhàolùn shū 肇論疏 (T1859), the foundational Tang Sān-lùn-school commentary on Sēngzhào’s Zhàolùn. The commentary is doctrinally rigorous and prosopographically informative, supplying biographical detail on Sēngzhào and Huìdá that does not appear in the standard hagiographic record. He is also credited (in fragmentary catalog references) with sub-commentaries on the Mūlamadhyamakakārikā and the Bǎilùn, but these have not survived.
