The Otley and Ilkley Joint Railway was a railway line running between the towns of Otley and Ilkley in West Yorkshire. The line was managed and run jointly by the Midland Railway (MR) and the North Eastern Railway (NER) and was 6.5 miles (10.46 km) long. Opened to passenger traffic on 1 August 1865 and freight traffic some months later, the line ran for almost 100 years before partial closure in July 1965 when the line to Otley closed. Today passenger services still run over the rest of the line as part of the West Yorkshire Passenger Transport Executive (WYPTE) Wharfedale Line.
