Zēng Zào 曾慥 (d. 1155), zì Duān bó 端伯, hào Zhì yóu zǐ 至遊子, was a Northern-Sòng scholar-official and bibliophile of Jìn jiāng 晉江 (Fú jiàn). Distant descendant of the Northern-Sòng statesman Zēng Gōng liàng 曾公亮. Two of his anthological works had enormous cultural impact: the Lèi shuō 類説 (leishu of literary excerpts) and — in the Daoist arena — his massive Dào shū 道樞 (KR5d0039) in 42 juàn, a topically-organized anthology of Daoist meditative, alchemical, and philosophical passages, compiled around 1151. The Dào shū is one of the most important Sòng Daoist compendia and a crucial resource for texts otherwise lost.
