Zhaozhou Congshen (Chinese: 趙州從諗; pinyin: Zhàozhōu Cōngshěn; Wade–Giles: Chao-chou Ts'ung-shen'; Japanese: 趙州従諗, romanized: Jōshū Jūshin; 778–897) was a Chán (Zen) Buddhist master who appears frequently in the koans of the Mumonkan and the Blue Cliff Record.

At the age of 18, he met Nánquán Pǔyuàn (南泉普願 748–835; J: Nansen Fugan), a successor of Mǎzǔ Dàoyī (709–788; J. Baso Do-itsu), and eventually received the Dharma from him.

[2] Zhaozhou is sometimes touted as the greatest Chan master of Tang dynasty China during a time when its hegemony was disintegrating as more and more regional military governors (jiédùshǐ) began to assert their power.

Zhaozhou's lineage died out quickly due to the many wars and frequent purges of Buddhism in China at the time, and cannot be documented beyond the year 1000.

"[3]Many koans in both the Blue Cliff Record and The Gateless Gate concern Zhaozhou, with twelve cases in the former and five in the latter being attributed to him.
