The Sun Yat Sen Nanyang Memorial Hall, also known as Wan Qing Yuan, and formerly as the Sun Yat Sen Villa, is a two-story colonial style villa in Balestier, Singapore. The villa is now a museum commemorating Sun Yat Sen (1866–1925), the founding father of the Republic of China who visited Singapore nine times between 1900 and 1911.
Located at 12 Tai Gin Road off Ah Hood Road in Balestier, the villa occupies an area of approximately 3,120 square metres (33,600 sq ft) and played a crucial role in the 1911 Xinhai Revolution by serving as the Tongmenghui's base in Nanyang (Southeast Asia) in the early 20th century.
