Zōngjiàn 宗鑑 (fl. early 13th c.) was a Southern Sòng Tiāntái 天台 school monk active in the Sìmíng 四明 (Níngbō) region. The preface to his major work, the Shìmén zhèngtǒng 釋門正統 (KR6r0018), is dated 1237 (Jiāxī 1). His sobriquet was Liángzhǔ 良渚.
The Shìmén zhèngtǒng is an eight-juan universal Buddhist history that establishes the Tiāntái patriarchal succession as the orthodox lineage of Chinese Buddhism — directly responding, from the Tiāntái side, to the historiographical claims of the Chán lamp-record tradition. The work was composed in the broader context of the Sòng-period TiāntáiChán polemic and of the contemporary Confucian zhèngtǒng 正統 (legitimate-succession) debates. It served as the immediate model and predecessor for 志磐’s much fuller Fózǔ tǒngjì (KR6r0012) of 1269.
宗鑑 left the work apparently incomplete at his death; the surviving Xuzangjing recension may not represent his finished plan. No further substantial biographical data is preserved.
