Caldecott Hill is a private housing estate, located along Thomson Road in the Central Region of Singapore.

Caldecott Hill is named after respected British colonial administrator and former Governor of Hong Kong Sir Andrew Caldecott, who had served in various posts around British Malaya (Officer Administering the Government of the Straits Settlements and High Commissioner for the Malay States in 1934) for nearly three decades.

Its successor Radio Malaya broadcast from Caldecott Hill until after Malaya's declaration of independence in 1957, when it relocated its main studio to Kuala Lumpur, and the new regional station Radio Singapura began broadcasting from its former studio.

[4][5] In December 2020, the land was sold for $280.9 million to Kuok Khoon Hong and his company Perennial Real Estate Holdings.
