Lin Zongsu (Chinese: 林宗素; 1878–1944) was a Chinese suffragist and writer. She founded the first women's suffrage organization in China and was one of China’s most noted political feminist activists in the Qing-early Republican period. She also became one of China’s first woman journalists and newspaper editors. As a journalist, she published widely on women’s rights and led several women’s organizations until democracy was suppressed in 1913. In later life, she taught in Singapore and ran a boating enterprise there which was able to finance her brother's newspapers in China. After a decade in Southeast Asia, she and her husband returned to China and lived in the southern part of the country where their business operations were located.
