Yu Zhengxie (1775–1840) was a Qing dynasty scholar from Yi county in modern-day Anhui province.

Along with his philological work, he was a noted critic of foot binding, female infanticide, and the cult of widow chastity.

While in Beijing, Yu assisted Ye Mingchen in the compilation of the 1818 edition of the Collected Statutes of the Great Qing [zh], and also wrote a history of his hometown.

For his stance on women's issues, Lin Yutang regarded him as one of the three pre-modern Chinese male feminists along with Yuan Mei and Li Ruzhen.
