The Municipal Corporations Act 1835 (5 & 6 Will. 4. c. 76), sometimes known as the Municipal Reform Act, was an Act of the Parliament of the United Kingdom that reformed local government in the incorporated boroughs of England and Wales. The legislation was part of the reform programme of the Whigs and followed the Reform Act 1832, which had abolished most of the rotten boroughs for parliamentary purposes.

The government of Lord Grey, having carried out reform of parliamentary constituencies, turned its attention to local government. In February 1833 a select committee was appointed "to inquire into the state of the Municipal Corporations in England, Wales, and Ireland; and to report if any, and what abuses existed in them, and what measures, in their opinion, it would be most expedient to adopt, with a view to the correction of those abuses".^[2] The committee made their report in June 1833, having inquired into a handful of boroughs. The committee found that:

The jurisdiction of the corporations is defective in some case in consequence of the town having been extended beyond the limits of the ancient borough; and in other cases it is objectionable from extending to places that are distant, and more properly falling within the jurisdiction of the county magistrates.

The principle which prevails of a small portion of corporators choosing those who are to be associated with them in power, generally for life, is felt to be a great grievance. The tendency of this principle is to maintain an exclusive system, to uphold local, political and religious party feelings, and is destructive of that confidence which ought always to be reposed in those who are intrusted with control, judicial or otherwise, over their fellow citizens…

The committee are further led to infer that corporations, as now constituted, are not adapted to the present state of society… To make corporations instruments of useful and efficient local government, it seems to be essential that the corporate officers should be more popularly chosen…[and] that their proceedings should be open and subject to control of public opinion.^[3]

The committee did not believe that they had sufficient powers to carry out a full review of the existing system. They instead recommended the appointment of a royal commission, and that the country be divided into districts with a commissioner responsible for enquiring into boroughs in each district.^[3]

The royal commission was appointed by letters patent passed under the great seal. The commission, which was dominated by Radicals, had eighteen members, with two assigned to each district or circuit:^[4][5]

• North Midland: Richard Whitcombe and Alexander Edward Cockburn
• Eastern: George Long and John Buckle
• South Western: Henry Roscoe and Edward Rushton
• Southern: John Elliot Drinkwater and Edward John Gambier
• Western: Charles Austin and James Booth
• Midland: Peregrine Bingham and David Jardine
• Northern: Fortunatus Dwarris and Sampson Augustus Rambull
• North-Western: George Hutton Wilkinson and Thomas Jefferson Hogg
• South-Eastern: Thomas Flowers Ellis and Daniel Maude

The commission's secretary was Joseph Parkes.

The Act established a uniform system of municipal boroughs, to be governed by town councils elected by ratepayers (termed 'burgesses'). The reformed boroughs were obliged to publish their financial accounts and were liable to audit. Each borough was to appoint a salaried town clerk and treasurer who were not to be members of the council.^{[citation needed]}

The Act reformed 178 boroughs. The Burgh Reform Act 1833 had already carried similar reforms in Scotland. Similar legislation would not be introduced in Ireland until the Municipal Reform Act 1840. There remained more than 100 unreformed boroughs, which generally either fell into desuetude or were replaced later under the terms of the Act. The last of these was not reformed or abolished until 1886. The Act did not extend to the City of London which remains a sui generis authority.^{[citation needed]} Many of the reformed boroughs had their municipal boundaries adjusted to match the parliamentary boundaries which had been reformed three years earlier under the Parliamentary Boundaries Act 1832.^[8][9]

The Act allowed unincorporated towns to petition for incorporation. The industrial towns of the Midlands and North quickly took advantage of this, with Birmingham and Manchester becoming boroughs as soon as 1838. Altogether, 62 additional boroughs were incorporated under the Act.^{[citation needed]}

The new corporations had annual elections, with a third of the councillors up for election each year. The council also elected aldermen to serve on the council, with a six-year term. Towns were divided into wards.^[10] The act also changed the enrollment of new freemen and burgesses in each of the boroughs, changing the criteria to be solely due to occupancy and payment of rates, and abolishing any previous criteria in earlier borough charters.^[11]

The Act was repealed "subject to the exceptions and qualifications in this Act mentioned" by section 5 of, and Part I of the First Schedule to, the Municipal Corporations Act 1882.

The list shows the style by which the unreformed corporation was known, and the date of its governing charter. In most cases this was the last in a succession of charters granted by a number of monarchs. In a few cases boroughs had no charter, or the charter was lost.^{[citation needed]}
