The Diocese of Ripon (Diocese of Ripon and Leeds from 1999 until 2014) is a former Church of England diocese, part of the Province of York. Immediately prior to its dissolution, it covered an area in western and northern Yorkshire as well as the south Teesdale area administered by County Durham which is traditionally part of Yorkshire. The cities of Ripon and Leeds were within its boundaries as are the towns of Harrogate, Richmond, Knaresborough, Hawes and Bedale and the surrounding countryside; its northern boundary was the River Tees.
