Ribble Valley is a local government district with borough status in Lancashire, England. Its council is based in Clitheroe, the largest town. The borough also includes the town of Longridge and numerous villages and surrounding rural areas. It is named after the River Ribble. Much of the district lies within the Forest of Bowland, a designated Area of Outstanding Natural Beauty.

The neighbouring districts are Pendle, Burnley, Hyndburn, Blackburn with Darwen, South Ribble, Preston, Wyre, Lancaster and North Yorkshire.

The district was created on 1 April 1974 under the Local Government Act 1972, covering the whole area of four former districts and parts of another three, which were abolished at the same time:

The new district was named Ribble Valley after the River Ribble which flows through the area. The new district was awarded borough status from its creation, allowing the chair of the council to take the title of mayor.

The Bowland Rural District had been in the West Riding of Yorkshire prior to the reforms, whereas the other parts had all been in Lancashire. The council was granted a coat of arms in 1975, which includes both the Red Rose of Lancaster and White Rose of York, referencing the two historic counties.

The parish of Simonstone was transferred from Burnley to Ribble Valley in 1987.

Ribble Valley Borough Council provides district-level services. County-level services are provided by Lancashire County Council. The whole borough is covered by civil parishes, which form a third tier of local government.

The council has been under no overall control since the 2023 election, being led by a Conservative minority administration.
