Lee Choon Seng (Chinese: 李俊承; pinyin: Lǐ Jùnchéng; Pe̍h-ōe-jī: Lí Tsùn-sîng; 1888—5 June 1966) was a businessman and philanthropist in pre-independence Singapore. He founded several companies, cultivated rubber plantations in Malaya and started Chinese banks in the region. Lee held leadership roles in several Chinese community organisations in Singapore, notably the Singapore Chinese Chamber of Commerce and Industry (SCCCI), and supported Sun Yat-Sen's revolutionary cause in China. In addition, he promoted the growth of Buddhism in Singapore by setting up several Buddhist institutions, including the Singapore Buddhist Lodge, and Poh Ern Shih Temple. In 2008, his life and contributions to society were commemorated in a memorial hall at the Ee Hoe Hean Club.
