The Borough of Onslow was a local government district immediately to the north of Wellington, New Zealand. Incorporated on 13 March 1890 it included the districts of: Wadestown, Crofton, Khandallah and Kaiwarra but not Johnsonville. It replaced the Kaiwarra Town Board, the Wellington District Roads Board and a small part of the very wide jurisdiction of the Hutt County Council. Johnsonville Town Board remained independent.

Most of the population, in Wadestown, amalgamated with Wellington City in 1907, the rest in 1919.
