The current flag of Hong Kong is adopted for post-colonial Hong Kong during the Third Session of the Seventh National People’s Congress.

The Regional Flag of the Hong Kong Special Administrative Region of the People's Republic of China depicts a white stylised five-petal Hong Kong orchid tree flower in the centre of a Chinese red field. Its design is enshrined in Hong Kong Basic Law, the territory's constitutional document, and regulations regarding its use, prohibition of use, desecration, and manufacture are stated in the Regional Flag and Regional Emblem Ordinance.
