The Municipality of Ashfield was a local government area in the Inner West of Sydney, New South Wales, Australia. It is about 10 kilometres (6.2 mi) west of the Sydney central business district. The municipality was proclaimed on 28 December 1871 as the "Borough of Ashfield", which changed to the "Municipality of Ashfield" in 1906. On 12 May 2016, Ashfield merged with Marrickville Council and the Municipality of Leichhardt to form the Inner West Council.

The last mayor of the municipality was councillor Lucille McKenna, a member of the Australian Labor Party.

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.

The municipality comprised the following suburbs and localities:

• Ashfield
• Dobroyd Point
• Haberfield
• Summer Hill

It also included parts of:

• Ashbury (shared with City of Canterbury)
• Croydon (shared with Municipality of Burwood)
• Hurlstone Park (shared with City of Canterbury)
• Croydon Park (shared with City of Canterbury and the Municipality of Burwood)

The "Borough of Ashfield" was proclaimed in the New South Wales Government Gazette on 28 December 1871 and was originally divided into two wards, North Ward and South Ward.

Local issues in the area, before the forced merge into Inner West Council, included the redevelopment of Ashfield Mall and concerns about overdevelopment in general; construction of the M4 East tunnel because it might lead to increased traffic and pollution; and the general state of the commercial area, which one councillor labelled 'Trashfield'. Also contentious was Ashfield Council itself. In 2003, it was described by the Daily Telegraph as one of the worst councils in Sydney after one councillor took out a restraining order against another. By 2008, another councillor was sacked for not being a bona fide resident of the municipality while other councillors had made outspoken comments on issues such as the Iraq War, bird flu, the Monarchy and 30 km/h speed limits within residential areas. In 2009, Councillor Nick Adams was given a six-month suspension from the Liberal Party of Australia for conduct deemed likely to "embarrass or cause damage to" the Party during an altercation with a journalist.

A 2015 review of local government boundaries recommended that the Municipality of Ashfield merge with the Municipality of Leichhardt and the Marrickville Council to form a new council with an area of 35 square kilometres (14 sq mi) and support a population of approximately 186,000. On 12 May 2016, Ashfield merged with Marrickville Council and the Municipality of Leichhardt to form the Inner West Council.

The former Ashfield Municipal Council was generally considered a safe Labor area. As the attached table shows, Labor outpolled all other parties in the area at the final federal, state and council elections before the merge. However, the Liberals and Greens had strong voices in the area with the Council electing a member of the Greens Party as mayor and the northern part of Ashfield was represented by a Liberal Party member in the NSW Parliament. Prior to the 1970s, the area was more conservative, generally returning members who were Free Trade, Nationalist, UAP or Liberal although it wasn't unheard of for Labor members to get elected during this period.

The final council was composed of four Labor councillors, four independents and four Liberals. The last mayor was Lucille McKenna, the Council's first woman mayor.

Ashfield Municipal Council was composed of twelve councillors elected proportionally as four separate wards, each electing three Councillors. All Councillors were elected for a fixed four-year term of office. The mayor and deputy mayor were elected for a one-year term by the councillors at the first meeting of the council in September. The last election was held on 13 September 2012, and the makeup of the council for the term 2012–16, in order of election by ward, was as follows:

Ward	Councillor		Party	Notes

Coat of arms of Municipality of Ashfield

Notes The arms of the Municipality of Ashfield were granted by the Lord Lyon King of Arms, College of Arms, in 1983 and resulted from a visit for Scottish week in 1982 by Sir Crispin Agnew of Lochnaw (Chief of the Clan Agnew), who suggested that the council pursue the granting of a Coat of Arms based on its early associations with Robert Campbell, an early landowner who named his estates "Ashfield Park", which gave the council its name. He was subsequently commissioned to design the arms, which were granted in 1983. Crest Above the Shield is placed a coronet appropriate to the Municipality (videlicet:- a mural coronet Proper masoned Sable), and on a Wreath of the Liveried is set for Crest a sun rising Or. Escutcheon Azure, five mullets (arranged to represent the constellation of the Southern Cross). Argent a chief gyronny of eight Or and Sable within a cordure azure charged of eight annulets Or, the chief with a fillet Argent in the lower part. Motto AGITE PRO VIRIBUS ("Act according to your strength") Symbolism The arms are based on arms of Robert Campbell, who registered his arms with Lord Lyon.

Ashfield Council launched a new logo and branding in August 2008, described as an "urban map" of various images representing various buildings and forms in the local area. This branding remained in use (with the arms retained for the most formal uses) until the council's amalgamation.
