The Pilmoor, Boroughbridge and Knaresborough Railway was a railway line in North Yorkshire, England, that connected Pilmoor on the East Coast Main Line with the towns of Boroughbridge and Knaresborough. The first part of the branch headed south-westwards from the East Coast Main Line and terminated at Boroughbridge. In 1875, the branch was extended again to meet the line at Knaresborough.

Boroughbridge is a town and civil parish in North Yorkshire, England. Historically part of the West Riding of Yorkshire, it is 16 miles (26 km) north-west of York. Until a bypass was built the town lay on the main A1 road from London to Edinburgh, which crosses the River Ure here.
