Dèng Yǒugōng 鄧有功 (fl. late Northern Sòng, before 1116) was a Daoist priest of the Tiānxīn zhèngfǎ 天心正法 tradition who held the rank “Recipient of the Shàngqīng Dàdòng register, Practitioner of the Tiānxīn Orthodox Method” (受上清大洞籙行天心正法). According to his own preface to the Shàngqīng gǔsuǐ língwén guǐlǜ (KR5b0145), he travelled for more than a decade between the Yùlóngguàn 玉隆觀 (Hóngzhōu Xīshān 洪州西山), the Tàipíngguàn 太平觀 (Lúshān 廬山), the Jiǎnjìguàn 簡寂觀 (Nánkāngjūn 南康軍), and the Língxiānguàn 靈仙觀 (Shūzhōu 舒州) collecting five separate manuscript witnesses of the Guǐlǜ corpus. He collated them, restored the missing portions of the Yùgé 玉格 and Xíngfǎ yíshì 行法儀式 sections, and submitted the resulting recension to the throne — a memorial implying a court audience in the late Huīzōng era. His preface (dated by internal reference to a year before 1116) is the principal source on the early transmission of the Tiānxīn zhèngfǎ. CBDB has no entry under this name. He should not be confused with the much earlier LiúSòng Daoist Dèng Yùzhī 鄧郁之 of Nányuè (see KR5b0136).
