Choi Hung Estate (Chinese: 彩虹邨; lit. 'rainbow estate') is a public housing estate in Ngau Chi Wan, Kowloon, Hong Kong. It was built by the former Hong Kong Housing Authority (屋宇建設委員會; Cǎihóng Cūn) and is now managed by the current Hong Kong Housing Authority (香港房屋委員會). It received a Silver Medal at the 1965 Hong Kong Institute of Architects Annual Awards.^[1]

Choi Hung Estate is located in Ngau Chi Wan and is surrounded by several of eastern Kowloon Peninsula's major roads. To the north is Lung Cheung Road; to the south Prince Edward Road East; to the west Kwun Tong Bypass and to the east Clear Water Bay Road.

The Hong Kong government granted the land to the Hong Kong Housing Authority to build a large housing estate in 1958. The blocks of the estate were completed between 1962 and 1964. An opening ceremony was held in 1963 with the presence of then Hong Kong Governor, Sir Robert Brown Black. A signboard commemorating the ceremony is located in the estate's Lam Chung Avenue.

Accommodating nearly 43,000 people, it was the largest public housing estate at the time. It subsequently attracted several prominent visitors, including Richard Nixon in 1964 (who became President of the United States in 1969), Britain's Princess Margaret in 1966, and Princess Alexandra in 1967.^[2]

In November 2023 it was reported that Choi Hung Estate was earmarked for redevelopment meaning that 43,000 residents will require rehoming.^[3]

The estate has 11 residential blocks, one car park, and five schools, with various shops and restaurants on the ground floor of each block. Roads in the estate connect the blocks to each other and to major roads.

According to the 2016 by-census, Choi Hung Estate had a population of 18,435. The median age was 48 and the majority of residents (96 per cent) were of Chinese ethnicity. Cantonese was the predominant usual spoken language (93 per cent), followed by other varieties of Chinese excluding Mandarin (4.5 per cent), non-English and non-Chinese languages (2 per cent), Mandarin (0.5 per cent), and English (0.3 per cent).

The average household comprised 2.5 persons. The median monthly household income of all households (i.e. including both economically active and inactive households) was HK$15,290.^[4]

The estate is photogenic and has become a tourism hot-spot.^[5][6] The most photographed view of the estate includes the basketball court and rainbow apartments behind.^[7] Some journalists and researchers have been vocal against the growing Instagram popularity of the area, criticising that it is a shallow view of the complex social history of the council estate in Hong Kong, as well as driving away locals who want to use the space.^[8][9] Though some locals have also begun selling photos for profit to tourists.^[9] It has been suggested that the location is popular not only for the aesthetics, but also because it allows the photographers and selfie-takers to feel as if they are in the middle of the world - compared to the more detached equally-aesthetic Hong Kong skyline shots.^[10] In 2017, a photograph of the building was shortlisted for the Arcaid Award, an architecture photography prize.^[11]

After featuring in a music video for Korean boyband Seventeen, the fame of the backdrop made the Hong Kong government tourist office begin heavily promoting it.^[12]

Choi Hung Estate is in Primary One Admission (POA) School Net 45. Within the school net are multiple aided schools (operated independently but funded with government money); no government primary schools are in this net.^[13]

Because the estate is accessible from major roads of Kowloon, the bus network is very convenient.
