Gāo Zhèngchén 高正臣 (fl. late 7th c.) was an early-Táng minor official and amateur literatus best known as the host of three poetic banquets held at his Luòyáng residence in the late seventh century — convivial gatherings of court figures including Chén Zǐ’áng 陳子昂, Láng Yúlìng 郎餘令, Xiè Wǎn 解琬, Zhōu Sījūn 周思鈞, and Zhāng Xī 張錫. The verse exchanged at these yàn 宴 was collected by Gāo himself and circulated as the Gāoshì sānyàn shījí 高氏三宴詩集 (KR4h0007). The Xīn Táng shū genealogy-table records that he served as cìshǐ of Xiāngzhōu 襄州; the colophon of his anthology (presumably appended by a later editor) claims he held office as Wèiwèiqīng 衛尉卿 and intermarried with the imperial Lǐ family during residence in Luòyáng — facts not in the standard histories. Otherwise unattested; CBDB has no entry. Nothing of his lifedates is known beyond his floruit in the late 660s–early 680s.
