Shù Xī 束晳 (c. 261–c. 303), zì Guǎngwēi 廣微, was a Western-Jìn polymath and bibliographer. Native of Yángpíng 陽平 Yuánchéng 元城 (modern Héběi). His family had originally borne the surname Shū 疏, changed to Shù 束 by a Hàn-era forebear. Best known as the principal scholar who collated, transcribed, and reported on the Jízhǒng 汲冢 bamboo-slip cache of 281 CE, alongside 荀勖 Xún Xù — his biographical chapter in Jìnshū 51 contains the canonical account of the Jízhǒng find, listing all the recovered texts: the Zhúshū jìnián, the Mù Tiānzǐ zhuàn (KR3l0092), the Zhōu shítián fǎ, the Zhōushū lùn Chǔ shì, the Zhōu Mùwáng měirén Shèngjī shì, and others. A poet and fù-writer of note (his Bǔwáng shī 補亡詩 reconstructs missing Shījīng poems), he served as Bóshì 博士 and Zhùzuò láng 著作郎 at the Mìshūshěng under Jìn Huìdì 晉惠帝. The variant character 束皙 (with 皙 rather than 晳) is also widely used in modern editions.
