This is a list of members of the House of Commons of the United Kingdom who were elected as independents or as a member of a minor political party. Excluded are the speaker, who traditionally stands for re-election without party affiliation, and MPs who were elected representing a major party but then defected or had the whip removed during a parliamentary term.

Great Britain

In Great Britain, the major parties are considered to be the Conservative and Unionist Party, the Labour Party, the Liberal Democrats and its forerunners, the Liberal Unionist Party, the various National Liberal parties, National Labour, the Scottish National Party and Plaid Cymru. Minor party and independent MPs have been rare in recent times: there were only 13 people elected as such in Great Britain between 1950 and 2023. However, there was a surge at the general election in 2024, with 4 Green MPs, 5 Reform MPs, and 5 independent candidates elected in constituencies with large Muslim populations, where there was opposition to the Labour Party due to their stance on the Israel-Gaza war.

1950–present

1919–1950

1832–1918

Excluded during this period are MPs from the Conservative and Liberal Parties, the Labour Party but not the Labour Representation Committee, the Liberal Unionist Party, the Whigs and the Tories. Before 1885 it becomes increasingly difficult to identify which MPs were independent, and F. W. S. Craig's classification is used.

Northern Ireland

MPs from the Democratic Unionist Party, Sinn Féin, Social Democratic and Labour Party or Ulster Unionist Party, including those Ulster Unionists who stood as part of the Conservative Party, are excluded. While these four are all currently regarded as major parties, each of these parties has at times held only a single seat (or none, in the cases of Sinn Féin, the SDLP, and the UUP), and for many years Sinn Féin was a banned organisation and did not contest elections. Also excluded are MPs from the Nationalist Party, which dissolved in 1977 but was formerly considered a major party.

Ireland

All MPs are listed except those from the Irish Unionist Alliance (affiliated to the Conservative Party during this period), the Nationalist Party, Sinn Féin, the Liberal Party, the Liberal Unionist Party and the Home Rule candidates.
