List of MPs elected in the 2019 United Kingdom general election

In the United Kingdom's 2019 general election, 650 members of Parliament (MPs) were elected to the House of Commons – one for each parliamentary constituency.

Parliament consists of the House of Lords and the elected House of Commons. This Parliament first met on 17 December 2019. After the swearing-in of members and the election of Speaker, the State Opening of Parliament took place on 19 December. The 2021 State Opening of Parliament began the second session on 11 May 2021. The 2022 State Opening of Parliament began the third session on 10 May 2022. The 2023 State Opening of Parliament began the fourth session on 7 November 2023. Notable newcomers to enter the House of Commons in this general election included future cabinet ministers Claire Coutinho, Richard Holden and Laura Trott.

The Parliament was marked by extraordinary political turmoil as the governments led by Boris Johnson, Liz Truss and Rishi Sunak had several high-profile political scandals and crises, which led to the Conservative Party seeing a major decrease in their popularity in opinion polling and the Labour Party and Liberal Democrats making gains from Conservatives, often by very wide margins. On 22 May 2024 Sunak announced that the 2024 general election would be held on 4 July. In light of this announcement, the House of Commons was dissolved by King Charles III on 30 May. The King also approved the prorogation of the fourth session, which took place on 24 May.
