Grantham and Stamford is a constituency^{[n 1]} in Lincolnshire represented in the House of Commons of the UK Parliament since 2019 by Gareth Davies, a Conservative.^{[n 2]}

Under the 2023 Periodic Review of Westminster constituencies, the constituency will be subject to major boundary changes, with Stamford being included in the re-established Rutland and Stamford constituency. The seat will be renamed Grantham and Bourne, to be first contested at the next general election.^[2]

Since 2010: The District of South Kesteven wards of All Saints, Aveland, Belmont, Bourne East, Bourne West, Earlesfield, Forest, Glen Eden, Grantham St John's, Green Hill, Greyfriars, Harrowby, Hillsides, Isaac Newton, Lincrest, Morkery, Ringstone, St Anne's, St George's, St Mary's, St Wulfram's, Stamford St John's, Thurlby, Toller, and Truesdale.

The constituency covers the towns Grantham^[3] and Stamford in Lincolnshire with surrounding villages. Most of the constituency was formerly in the Stamford and Spalding constituency. As well as the two Lincolnshire constituencies that it neighbours (Sleaford and South Holland), it neighbours Rutland and Melton to the west, and North West Cambridgeshire to the south. All five are academically considered, based on results in recent elections, Conservative safe seats.

This is a large rural seat in southern Lincolnshire. Grantham and Stamford are at the extreme north and south of the seat, with a large swathe of agricultural countryside between them, dotted with small rural villages. The only other large settlement in the seat is the rapidly growing town of Bourne, situated at the west of the Lincolnshire Fens. Food processing and agriculture are the major industries.^[4]

Politically, Grantham is associated with former Conservative Prime Minister Margaret Thatcher, who was born and raised in the town. However, the town of Grantham itself probably has the biggest Labour Party support of the constituency. The rural part of the seat and the historical town of Stamford outweigh any Labour votes in Grantham, and it is normally a safe Conservative seat. The history of Conservative representation was briefly interrupted between 2007 and 2010 when the sitting Conservative MP, Quentin Davies^[4][5] defected to Labour, as well as 2019 when an MP, Nick Boles, left the Conservative Party.

Workless claimants were in November 2012 significantly lower than the national average of 3.8%, at 2.8% of the population based on a statistical compilation by The Guardian.^[6]

The whole constituency lies within the area served by Lincolnshire County Council and South Kesteven District Council.
