The 1890 Wellington 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.
Background.
The incumbent mayor Charles Johnston declined to stand for a second term. Johnston's declination left the field open and two councillors Arthur Winton Brown (also a former mayor) and Charles Frederick Worth were nominated for the mayoralty. It was the first mayoral election since 1887 that had been contested.
