Yú Dá 俞達 (fl. late nineteenth century) is the attributed author of the romantic novel Qīnglóu Mèng 青樓夢 (Dream of the Green Bower) in 64 chapters (KR4k0206). Very little is known of his biography. The CBDB records him with id 85025 and a floruit year of 1884, with no birth or death years given. He is not to be confused with the far more prominent scholar 俞樾 Yú Yuè (1821–1907), whose surname is homophonous.
Qīnglóu Mèng is Yú Dá’s only known work. The novel romanticizes the world of cultured courtesans in the Tóngzhì-Guāngxù era and belongs to the qīnglóu 青樓 subgenre of late Qīng fiction. An anonymous copy of the same text is also preserved in the Kanripo corpus as KR4k0204.
