Yang Huimin (traditional Chinese: 楊惠敏; simplified Chinese: 杨惠敏; pinyin: Yáng Huìmǐn; March 6, 1915 – March 9, 1992) was a Girl Guide during the 1937 Battle of Shanghai who supplied a flag and brought supplies to besieged defenders of the Sihang Warehouse.

Her actions proved inspiring to the defenders, who flew the flag the next daybreak in front of thousands of watching eyes across the bank of the Suzhou Creek.

Yang had studied physical education in Shanghai and was a member of the Girl Scouts when the war broke out.

Her involvement in the Sihang Warehouse defense is featured in the 1976 Taiwanese film Eight Hundred Heroes with Brigitte Lin playing her role.

In 2020, Yang is portrayed by Tang Yixin in the Chinese historical war drama The Eight Hundred, which became the second highest-grossing film of 2020.
