Malton, also called New Malton, was a constituency of the House of Commons of the Parliament of England in 1295 and 1298, and again from 1640, then of the Parliament of Great Britain from 1707 to 1800 and of the Parliament of the United Kingdom from 1801 to 1885. It was represented by two Members of Parliament until 1868, among them the political philosopher Edmund Burke, and by one member from 1868 to 1885.

The constituency was divided between the new Thirsk and Malton division of the North Riding of Yorkshire and the Buckrose division of the East Riding of Yorkshire from 1885.

The constituency consisted of parts of the St Leonard's and St Michael's parishes of New Malton in the North Riding until the Great Reform Act of 1832; the borough at that point included 791 houses and had a population of 4,173 in the 1831 census. The Reform Act expanded the boundaries to include the whole of those two parishes, as well as that of Old Malton and of the adjoining town of Norton in the East Riding, increasing the population to 7,192 and encompassing 1,401 houses.

The right of election in Malton was vested in the scot and lot householders of the borough, of whom there were about 800 in 1832. In practice the seats were generally in the gift of the landowner, Earl Fitzwilliam (and were frequently held by one of that family, often by the heir to the Earldom who had the courtesy title Viscount Milton); at an earlier period the borough was similarly dominated by the Watson-Wentworth family, and was used as a form of government patronage when the Marquess of Rockingham was Prime Minister.
