Chéng Wěiyuán 程偉元 (courtesy name Xiǎoquán 小泉; active c. 1790s) was a Qīng-dynasty printer and man of letters. He is known chiefly as the co-publisher of the first 120-chapter printed edition of Hónglóu Mèng 紅樓夢 in 1792, together with Gāo È 高鶚. His preface claims he spent years collecting manuscript fragments of the final 40 chapters of the novel. His exact biographical details — birth and death dates, native place, and official career — remain largely unknown. No confident CBDB match has been located.
