Péng Qǐfēng 彭啟豐 (1701–1784, zì Zhǐtíng 芷庭), eminent Qīng official and belletrist of Chángzhōu 長洲 (Sūzhōu). Yōngzhèng 5 (1727) jìnshì zhuàngyuán 進士狀元 — the top-rank graduate of his cohort, like his grandfather Péng Dìngqiú 彭定求 before him, the Péngs of Sūzhōu being one of the rare houses to produce two zhuàngyuán in three generations. He served successively as Hànlín xiūzhuàn 翰林修撰, Zhèjiāng tídū xuéyuàn 浙江提督學院 (provincial examination commissioner), Gōngbù zuǒ shìláng 工部左侍郎 (left vice-minister of Works) — the position he held when, in 1757, he wrote the preface to KR3em024 Hóukē zhǐzhǎng of his fellow-Sūzhōu Zhāng Zōngliáng — and finally rose to bīngbù shàngshū 兵部尚書 (Minister of War).
His CBDB record (id 56860) gives the conventional 1701–1784 bracket; the CBDB note records that Qīngdài rénwù shēngzú niánbiǎo 清代人物生卒年表 places his birth on the 11th day of the 12th month of Kāngxī 40, which corresponds in the Gregorian calendar to 8 January 1702.
His literary collection is the Zhìtíng wénjí 芷亭文集 (variant orthography of his hào); the 1757 preface to Hóukē zhǐzhǎng is preserved in the front matter of the published medical book and remains his best-known intervention into a non-literary field.
