Dèng Càn 鄧粲 (zì Wèizǔ 蔚祖; fl. late 4th century CE) was an Eastern Jìn writer and historian, native of Xiāngzhōu 湘州 (modern Hunan). His biography is in Jìn shū 82, where he is grouped among the court historians. Known for his unconventional, detached temperament (xiān dá 閑達), he was associated with the intellectual circles of Héng’yáng 衡陽 in the south. He composed a Jìnjì 晉紀 (Record of the Jin) covering the Eastern Jìn dynasty from its founding under Emperor Yuán 元帝; the Suí shū jīngjí zhì records this at 10 juǎn. After the new Tang Jìn shū was compiled (648 CE), the work fell into disuse and was lost; 湯球 (Táng Qiú, 1804–1881) reconstructed fragments as part of the Jiǔjiā Jiù Jìnshū Jíběn 九家舊晉書輯本 — see KR4k0338. CBDB has no entry for Dèng Càn, consistent with the database’s focus on Táng-Qīng figures.
