The City of Knox is a local government area in Victoria, Australia in the eastern suburbs of Melbourne.

On 23 May 1889, the riding was severed to create the Shire of Fern Tree Gully, which extended as far east as Olinda and Monbulk in the Dandenong Ranges.

A plebiscite to determine local residents' views led to the creation of the Shire of Knox on 9 October 1963, which was proclaimed on 16 November 1963 by the Governor of Victoria.

[6][7] On 15 December 1994, the City of Knox was one of the few councils (and one of only four in Melbourne) to survive the statewide amalgamation and its boundaries extended to add the suburb of Upper Ferntree Gully and part of Lysterfield from the former Shire of Sherbrooke.

[2] At present, the City of Knox has nine wards, each electing one councillor for a period of four years.
