The 1885 United Kingdom general election was held from 24 November to 18 December 1885. This was the first general election after an extension of the franchise and redistribution of seats. For the first time a majority of adult males could vote and most constituencies by law returned a single member to Parliament, fulfilling one of the ideals of Chartism to provide direct single-member, single-electorate accountability. It saw the Liberals, led by William Gladstone, win the most seats, but not an overall majority. As the Irish Nationalists held the balance of power between them and the Conservatives who sat with an increasing number of allied Unionist MPs (referring to the Union of Great Britain and Ireland), this exacerbated divisions within the Liberals over Irish Home Rule and led to a Liberal split and another general election the following year.
The 1885 election saw the first socialist party participate, with the Social Democratic Federation led by H. M. Hyndman standing three candidates.
