Péng Bǎichuān 彭百川 (fl. late 12th — early 13th c.), zì Shūróng 叔融, was a late-Southern-Sòng scholar from Méishān 眉山 (in Sìchuān, the celebrated home of the Sū 蘇 family). He is known almost solely from his one substantial work, the Tàipíng zhìjī tǒnglèi 太平治迹統類 KR2e0014, a 30-juǎn (originally 40-juǎn) topical compendium of Northern-Sòng court affairs and ministerial careers — to which Mǎ Duānlín’s Wénxiàn tōngkǎo records a now-lost 33-juǎn hòu jí covering post-Jìngkāng affairs. He belongs to the same Sòng-loyalist documentary-historiographical milieu as Lǐ Xīnchuán 李心傳 (compiler of the Jiànyán yǐlái cháoyě záji 建炎以來朝野雜記 and the Jiànyán yǐlái xìnián yàolù 建炎以來繫年要錄). His birth and death years are not preserved.
