Hilton Cheong-Leen, CBE, JP (Chinese: 張有興; 6 August 1922 – 4 January 2022) was a Hong Kong politician and businessman.

He had been a long-time chairman of the Hong Kong Civic Association, one of the two quasi-opposition political groups in the post-war Urban Council.

He continues to be the honorary life president of the Hong Kong Watch Manufacturers Association.

[7] At the time the Urban Council elections, the only direct elections in the colony at the time, were dominated by Brook Bernacchi's Reform Club of Hong Kong, Cheong-Leen founded the Hong Kong Civic Association in 1954 with Roger Lobo and A. de O.

[2] Cheong-Leen was the founding secretary-general of the association and was in the first meeting at a bar on the mezzanine floor of Jimmy's Kitchen in Theatre Lane, Central.

[1] As the representative of the association, he visited London and New York and met with the Colonial Office officials and Members of Parliament (MPs) of different parties including William John Peel, son of Hong Kong Governor Sir William Peel, and United Nations officials Ralph Bunche and Benjamin Victor Cohen over constitutional reform and other issues respectively in the 1950s.

[3][5] He was also vice-chairman of the United Nations Association of Hong Kong led by Ma Man-fai, whom he befriended during their lives in Kunming.

The Civic Association at the time positioned itself as more pro-middle-class and moderate as compared to the Reform Club.

In the same year, Cheong-Leen led a delegation to London to make their case to British officials, but their call was not heeded by the government.

[9] He was first appointed an unofficial member of the Legislative Council of Hong Kong on 1 May 1973 by Governor Sir Murray MacLehose with Guy Sayer to fill the vacancies left by retired H. J. C. Browne and deceased Mary Wong Wing-cheung.

[1] He retired from the Legislative Council on 31 August 1979 along with James Wu Man-hon after six years of service and were succeeded by Hu Fa-kuang and Wong Po-yan.

[1] Their fourth child, Flora Cheong-Leen is a famous ballerina and designer who was married to actor Russell Wong.
