Kendal, once Kirkby in Kendal or Kirkby Kendal, is a market town and civil parish in the unitary authority of Westmorland and Furness, England. It lies within the River Kent's dale, from which its name is derived, just outside the boundary of the Lake District National Park. In the Domesday Book of 1086, the area was collected under Yorkshire. The area came under the Honour of Lancaster before the barony split.
