Swaledale is a valley in North Yorkshire, England. It is one of the Yorkshire Dales, which are part of the Pennines, and within the Yorkshire Dales National Park. It is named after the River Swale, which runs through it. Swaledale is the most northerly of the major dales.

The Yorkshire Dales are a series of valleys, or dales, in the Pennines, an upland range in England. They are mostly located in the ceremonial county of North Yorkshire, but extend into Cumbria and Lancashire; they were historically entirely within Yorkshire. The majority of the dales are within the Yorkshire Dales National Park, created in 1954. The exception is the area around Nidderdale, which forms the separate Nidderdale Area of Outstanding Natural Beauty.
