The Fylde (//) is a coastal plain in western Lancashire, England. It is roughly a 13-mile-long (21-kilometre) square-shaped peninsula, bounded by Morecambe Bay to the north, the Ribble estuary to the south, the Irish Sea to the west, and the foot of the Bowland hills to the east which approximates to a section of the M6 motorway and West Coast Main Line.
It is a flat, alluvial plain; parts of which have deposits of and were once dug for peat, and it is the western part of an area formerly known as Amounderness. The River Wyre meanders across the Fylde from Garstang on the eastern edge, westwards towards Poulton and then northwards to the sea at Fleetwood. The area north and east of the tidal Wyre, known as Over Wyre, is the more rural side of the river. The Fylde is roughly trisected by the M55 motorway and A586 road.
The west coast is almost entirely urban, containing the towns of Fleetwood, Cleveleys, Blackpool, St Annes and Lytham; with Thornton, Carleton and Poulton-le-Fylde not far inland. This area forms the Blackpool Urban Area. The central southern part of the Fylde includes the smaller towns of Kirkham and Wesham. The rest of the Fylde is rural, containing villages that include Freckleton, Warton, Wrea Green, Great Eccleston, Hambleton, Knott End and Pilling.
