Knott End-on-Sea is a village in Lancashire, England, situated on the southern side of Morecambe Bay, across the Wyre estuary from Fleetwood. Although there is no through road (to get there one has to pass through neighbouring Preesall), the village is in fact the main commercial centre for the Over Wyre area. As well as a variety of shops and cafes, Knott End has its own pub (the Bourne Arms), county library, NatWest bank and golf club. Buses run regularly from Knott End to Blackpool, Garstang, Lancaster and Fleetwood, and there is also a seasonal three-minute ferry crossing to Fleetwood.
Knott End also has two clubs, The Squash and Knott End Working Men's Club. Hackensall Hall is reputed to be named after an invading Viking named Haken.
