Silas Aaron Hardoon (Chinese: 哈同; pinyin: Hātóng; c. 1851– June, 1931) was a wealthy businessman and well-known public figure in the city of Shanghai in the early 20th century.

In 1868 Silas Aaron Hardoon traveled to the city of Shanghai (China), where he was employed by David Sassoon & Company as a rent collector and watchman.

[3] Shrewd investments, particularly in properties on Shanghai's "Fifth Avenue," Nanking Road, eventually made him one of that city's wealthiest inhabitants.

In early 1920 the future Chinese leader Mao Zedong stayed in Shanghai at a property owned by Hardoon on present-day Anyi Road.

[citation needed] However, Ezra Salch Hardoon, who represented the other Iraqi relatives, continued to petition the Chinese courts both before and after the Communist take-over in 1949.
