From 1832 – 1918, the village of Corby was part of the North Northamptonshire constituency, which consisted of most of the Soke of Peterborough, the towns of Oundle and Thrapston and the surrounding villages and hamlets of north-eastern Northamptonshire.[3]
The North Northamptonshire constituency boundaries were changed slightly in 1885, with some of the constituency being transferred to the newly created Mid Northamptonshire constituency. However, Corby remained within the revised constituency of North Northamptonshire.[4]
The North Northamptonshire constituency was abolished in 1918 for that year's general election, and from 1918, Corby was part of the Kettering constituency.
Corby remained part of the Kettering constituency until 1983. The Parliamentary seat of 'Corby' was created due to population increases in and around the town of Corby for the 1983 general election. Since creation, the Corby constituency has been a marginal seat being won by the party that won the national election at each general election since its creation. The first Member of Parliament elected for the constituency in 1983 was William Powell, who represented the Conservatives for three sessions of Parliament until 1997. Labour then held the seat until 2010.
On 6 August 2012, MP for the seat since 2010 Louise Mensch (formerly Louise Bagshawe) announced she was resigning, triggering a by-election held on 15 November 2012. Labour's Andy Sawford won, becoming the first Labour MP for the seat since Phil Hope was defeated in 2010, and only the second in the seat's history. This was Labour's first by-election win from a Conservative since the 1997 Wirral South by-election. At the 2015 general election Tom Pursglove standing for the Conservatives won with a small majority. He won again with a similar margin in 2017 and in 2019 Tom Pursglove took the seat for the third time, but with a majority of over 10,000, turning Corby into a non-marginal seat by Conservative Party standards.
At the 2024 general election, the seat was gained by Labour's Lee Barron amidst their national landslide victory, continuing the seat's bellwether streak of voting for the party that won nationally at every general election since its creation in 1983.

The constituency was created in 1983 from parts of the seats of Kettering and Wellingborough. It is named after the town of Corby in Northamptonshire, and also covers much of the local government district of East Northamptonshire, but excluding Rushden and Higham Ferrers which are in the Wellingborough constituency. The seat is a highly marginal contest between the Tories and Labour, with Labour's vote strongest in the town of Corby itself, against the solidly Conservative rural areas of East Northamptonshire.[6]
The constituency was sometimes informally called "Corby and East Northamptonshire",[7] but the 2007 Parliamentary Constituencies Order[8] and Whitaker's Almanack both make it clear that, until 2024, its official name was "Corby".
