Dagenham was a borough constituency represented in the House of Commons of the UK Parliament that elected one Member of Parliament (MP) by the first past the post system of election. It was replaced at the 2010 general election largely by Dagenham and Rainham.

1945-1974: The Municipal Borough of Dagenham.

1974-1983: The London Borough of Barking wards of Chadwell Heath, Eastbrook, Fanshawe, Heath, River, Valence, and Village.

1983-2010: The London Borough of Barking and Dagenham wards of Alibon, Chadwell Heath, Eastbrook, Fanshawe, Heath, Marks Gate, River, Triptons, Valence, and Village.

Following their review of parliamentary representation in North London, the Boundary Commission for England have created a new constituency of Dagenham and Rainham.

Before 1945 this Dagenham and surrounds area was part of the Romford constituency.

The MP for the predecessor seat since 1935, Labour's John Parker, stood again on each occasion in this smaller successor area, representing it until 1983. Parker was the last serving MP to have been elected before the Second World War, and with 48 years in Parliament, remains the longest-serving Labour MP in history.

Dagenham was held by Labour its inception and was without exception rated by election predictions as a safe seat. Dagenham hosts an at times shrinking skilled manual industry such as the Ford Motor Company works, which downscaled production in 2001, leading to replacement distribution and warehousing businesses as well as local regeneration under the Thames Gateway project from 2005 however higher than national unemployment immediately, including following the seat's abolition. See the main successor seat, Dagenham and Rainham for statistics. The largest-polling opposition candidate was Conservative since 1979, with the Liberal Party a greater or equal opponent in elections before that, vying for second place with that party.
