# Grantham (UK Parliament constituency)

Grantham was a Parliamentary constituency in Lincolnshire, England.
The constituency was created in 1468 as a parliamentary borough which elected two Members of Parliament (MPs) to the House of Commons of the Parliament of England until the union with Scotland, and then to the Parliament of Great Britain until the Act of Union 1800 established the Parliament of the United Kingdom.
The parliamentary borough had its representation reduced to one MP in 1885, and was finally abolished in 1918, the name transferring to a new county division which elected one MP. The county constituency was abolished for the 1997 election, and the area formerly covered by this constituency is now mostly in Sleaford and North Hykeham. Grantham became part of the new constituency of Grantham and Stamford.
The 2023 Periodic Review of Westminster constituencies proposes to re-establish the seat in its revised proposal.

## Boundaries

The constituency was based on Grantham, a market town on the River Witham.
