The Forest of Pendle is a hilly area to the east of Pendle Hill in eastern Lancashire, roughly defining the watershed between the River Ribble and its tributary the River Calder. The area is not a forest in the modern sense of being heavily wooded, and has not been so for many centuries. Historically a somewhat larger area than the modern forest was one of the several royal forests of the area, under the control of Clitheroe Castle, or Honour of Clitheroe. Over its history, the forest has gone from being protected and regulated as a medieval royal forest, to being labelled as an Area of Outstanding Natural Beauty.
The forest is not coterminous to the modern local government district of Pendle, which is larger, and the modern version of the forest has come to contain areas to the north and east of Pendle Hill which are partly in the district of Ribble Valley.
