The 1888 Wellington City mayoral election was part of the New Zealand local elections held that same year to decide who would take the office of Mayor of Wellington for the following year.
The chairman of the Wellington Harbour Board, John Duthie, was elected mayor unopposed.[1] Initially there was another contestant, former city councillor Kennedy Macdonald, who withdrew from the election meaning a poll was not necessary.[2] It was the first of two successive elections where the mayoralty was uncontested.
