Lancaster and Fleetwood was a constituency[n 1] created in 2010 represented in the House of Commons of the UK Parliament.

[2] Following its review of parliamentary representation in Lancashire, the Boundary Commission created a new Wyre and Preston North constituency, contested first at the 2010 general election, which split the previous linking of Lancaster and Wyre.

As a consequence, Lancaster and the coastal town of Fleetwood were attached for parliamentary purposes.

[3] Ollerenshaw attempted to regain the seat at the 2017 general election but Smith won again, significantly increasing her majority to over 6,500.

The new seat of Lancaster and Fleetwood was subject to public consultation following the decision to create a new seat in Lancashire in the run-up to the 2010 general election, which caused major consequential changes to the central and southern parts of the county.
