Chan Tseng-hsi (Chinese: 陳曾熙; pinyin: Chén Zēngxī; abbreviated as T.H. Chan; 1923 – 8 March 1986) was a Hong Kong entrepreneur who founded the Hong Kong–based real estate company Hang Lung Group.

Born and raised in the province of Guangdong, China, Chan moved to British Hong Kong in the 1940s because of the Chinese Civil War. He took an entry-level job in a bank[which?] and eventually built a successful real estate business. According to his son Gerald, he used to loan money to his friends to pay for their children's school fees. His wife, Tan Chingfen, was a nurse who, in the 1950s, gave cholera vaccinations to the neighbourhood children in the family kitchen.

After Gerald got a fellowship for his doctoral studies at Harvard, Chan was proud of his son, but disturbed that Gerald was taking the place of someone who could not pay. He told a friend, "We have the means to pay tuition. Why is Gerald taking the scholarship away from someone else?"

UMass Chan Medical School is named after him and the Tan Chingfen Graduate School of Nursing is named after his wife because of a donation from his family in his memory.
