The Pennines, also known as the Pennine Chain or Pennine Hills, are a more-or-less continuous range of hills and mountains running between three regions of Northern England: North West England on the west, and North East England and Yorkshire and the Humber on the east. 

Commonly described as the "backbone of England", the range stretches northwards from the Peak District at the southern end, through the South Pennines, the Yorkshire Dales and North Pennines to the Tyne Gap, which separates the range from the Cheviot Hills across the Anglo-Scottish border.

The region is widely considered to be one of the most scenic areas of the United Kingdom. The North Pennines and Nidderdale are designated Areas of Outstanding Natural Beauty (AONB), as are Bowland and Pendle Hill. Parts of the Pennines are incorporated into the Peak District National Park and Yorkshire Dales National Park. Britain's oldest long-distance footpath, the Pennine Way, runs along most of the Pennine Chain and is 268 miles (429 km) long.
