Dù Gōngzhān 杜公瞻 (fl. early 7th c.) was a Suí-period court compiler, native of Jīngzhào 京兆, who held the office of Compiler-in-Waiting (Zhe-zuò zuǒláng 著作佐郎) concurrently with that of Gentleman Cavalier Attendant (sànqí shìláng 散騎侍郎) at the court of Suí Yángdì 隋煬帝. He is not recorded in either the Suí shū or the Běi shǐ; the single anecdote that fixes his social context is preserved in the Tánsōu 談藪, where the Suí Jīngzhào Dù Gōngzhān is described as having invited a certain Yáng Jiè 楊玠 to his house for wine and a session of mock-disputation. His one extant work is the Biānzhū 編珠 (KR3k0002) in 4 juan (only 2 juan surviving in the Yǒnglè dàdiǎn recension), an allusion-treasury produced by imperial command in Dàyè 大業 7 (611) to assist Yángdì in the composition of záyǒng 雜詠 and xīntǐ 新體 verse — though the Sìkù compilers note the possibility that the surviving text is a partial late-Míng reconstruction.
