Sir John Kennedy-Good KBE QSO JP (8 August 1915 – 11 July 2005) was a New Zealand politician.

Kennedy-Good was educated at Southland Boys' High School[1] and graduated from the University of Otago with a Bachelor of Dental Surgery in 1940.

[1] Kennedy-Good became involved in local politics through the issue of fluoridation of Lower Hutt's water supply, which he supported.

The Citizens' Association, who had a majority on the council, surprisingly did not select Kennedy-Good for the 1971 election instead choosing the deputy mayor (and 1968 candidate) Dave Hadley instead.

As a result Kennedy-Good formed his own "combined" electoral ticket, consisting of candidates who were previously Citizens' and Labour affiliated, with which to contest the election.

[8] In an evenly divided poll Kennedy-Good narrowly edged out former Labour councillor John Seddon to win the election (Hadley came third).

[11] The latter years of his mayoralty were dominated by the construction of Queensgate Shopping Centre and one of his final acts as mayor was its official opening.
