Brigg and Cleethorpes was a constituency on the south bank of the Humber estuary which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first-past-the-post voting system.

This safe Conservative seat was held by Michael Brown for the entire period of its existence.

The Borough of Cleethorpes, and the Borough of Glanford wards of Abbey, Barton-upon-Humber Bridge, Barton-upon-Humber Park, Brigg, Goxhill, Humber, Kirton, North Ancholme, Scawby, South Ancholme, Ulceby, Wold, and Wrawby.

In 1997, an extra seat was allocated to the Humber, with the result that constituencies in the region needed to cover a smaller population.

The new constituency of Cleethorpes was created with this in mind, with the remainder of the constituency forming part of Brigg and Goole.
