Marrickville Council was a local government area located in the inner west region of Sydney, Australia. It was originally created on 1 November 1861 as the "Municipality of Marrickville". On 12 May 2016, Marrickville Council was forcibly merged with Ashfield and Leichhardt councils into the newly formed Inner West Council. In December 2021, a majority of voters in Inner West Council voted in favour of reversing the 2016 merger and separating the three pre-existing councils of Ashfield, Leichhardt and Marrickville.
