Chan Tseng-hsi (Chinese: 陳曾熙; pinyin: Chén Zēngxī; 1923 – 8 March 1986) was a Hong Kong entrepreneur who founded the Hong Kong-based real estate company Hang Lung Group.^[1]

Born and raised in 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 mother was a nurse who, in the 1950s, gave cholera vaccinations to the neighbourhood children in the family kitchen.^[2]

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 couldn't pay. He told a friend, "We have the means to pay tuition. Why is Gerald taking the scholarship away from someone else?"^[2]

In 2014, his sons Ronnie and Gerald donated $350 million to Harvard University, which named the Harvard T.H. Chan School of Public Health after him.^[2][3] Harvard officials said the money would be used in four areas: pandemics, including obesity, cancer, and the Ebola outbreak in West Africa; harmful environments, including pollution and violence; poverty and humanitarian crises; and failing health systems.^[3]

In 2021, the Chan family made an unrestricted gift of $175 million to the UMass Medical School, which changed its name to UMass Chan Medical School in recognition of this donation.^[4]

In March 2022, the Morningside Academy for Design was founded with a $100 million gift from the Morningside Foundation, the philanthropic arm of the T.H. Chan family.^[5]
