Healey Nab or "The Nab" is an area of countryside owned partly by Lancashire County Council containing rolling hills, moorland, woodland, ponds and streams to the east of Chorley, Lancashire, between the M61 and the West Pennine Moors. To its southeast is Anglezarke Reservoir and to its northeast is White Coppice. The name "Healey Nab" is derived from heagh (high) and ley (woodland). "Nab" is believed to derive from the Middle-English nabb, meaning promontory or headland.
