John Arthur Blackwood (3 November 1904 – 6 August 1973) was a British Hong Kong businessman.
He was the taipan of Butterfield & Swire and chairman of Cathay Pacific Airways.
[1] Between 1954 and 1955, he was the chairman of the Hong Kong General Chamber of Commerce, replacing Cedric Blaker.
[2] He represented the Chamber of Commerce as an Unofficial member of the Legislative Council of Hong Kong from 1954 to 1955.
[3] In the Legislative Council, he strongly opposed the introduction of section 27 to the Inland Revenue Ordinance, which allowed the government (in case of doubt as to the provenance of a profit) to consider lack of overseas taxation as evidence that the profit in question arose in Hong Kong, thus becoming liable to taxation in Hong Kong.
