Bramhope Tunnel is on the Harrogate Line between Horsforth station and the Arthington Viaduct in West Yorkshire, England. Services through the railway tunnel are operated mainly by Northern. The tunnel was constructed during 1845–1849 by the Leeds and Thirsk Railway. It is notable for its length and its Grade II listed, crenellated north portal. The deaths of 24 men who were killed during its construction are commemorated in Otley churchyard by a monument that is a replica of the tunnel's north portal.
