John Gibbs Churchill OBE JP (7 February 1905–2 December 1975) was a New Zealand trade unionist and local politician.

[1] In 1950 Churchill won a seat on the Wellington City Council on a Labour ticket which he was to hold until 1964 when he decided not stand for re-election.

Political scientist George Betts said Churchill was one of Wellington's most influential and competent councillors who bucked the trend which saw union secretaries regularly fail to be elected to local bodies.

[3] In 1957 Churchill suggested to the Town Clerk that the council design a flag for the city for official occasions and to be flown at civic buildings, parks and reserves.

He lost in a ballot among fellow councillors to Harry Nankervis after the 1959 elections and again in 1962 to Denis McGrath (both from the Citizens' Association which held majorities on the council).

[6] The council decided against holding a by-election to fill the vacancy caused by his retirement and his vacated seat remained empty until the 1965 elections.

Later an allegation surfaced that Citizens' Association members had met privately the morning before and had been influenced on nominating Binnie over Churchill.

[11] In 1973 he was appointed to the newly-constituted board of trustees of the National Art Gallery, Museum and War Memorial having been nominated by local bodies.

[1] Churchill Park, located in Seatoun, was named after him in recognition of his many years as chairman of the Wellington City Council Reserves Committee.
