The Antiquities and Monuments Office (AMO) is a Hong Kong government organization established in 1976 under the Antiquities and Monuments Ordinance to protect and preserve historic monuments. Housed in the Former Kowloon British School, the AMO is responsible for identifying, recording and researching buildings and items of historical interest, as well as organising and coordinating surveys and excavations in areas of archaeological significance. The Commissioner for Heritage's Office under the Development Bureau of the Hong Kong government currently manages the Office.

The Antiquities Advisory Board (AAB) is a statutory body of the Hong Kong Special Administrative Region with the responsibility of advising the Antiquities Authority on any matters relating to antiquities and monuments. The AAB was established in 1976 along with the Antiquities and Monuments Office (AMO) when the Antiquities and Monuments Ordinance (Cap. 53) was enacted, and comprises members appointed by the Chief Executive. The corresponding governmental ministry is the Development Bureau, and executive support for the AAB is provided by the AMO which is under the Development Bureau.
