Arthington is a small village in Wharfedale, in the City of Leeds metropolitan borough in West Yorkshire, England. It is a civil parish which, according to the 2001 census, had a population of 561 and is in the LS21 postcode district with Otley as its post town. It is in the Otley ward of the City of Leeds, and the Leeds North West parliamentary constituency.
It used to be a railway junction (see Arthington railway station), where the (now-closed) line to Pool-in-Wharfedale station, Otley station, Ilkley station, and on to Skipton station joined the still open Harrogate Line from Leeds to Harrogate station.
It is at the northern end of the Bramhope Tunnel. There is a memorial to the workers killed digging the tunnel near the church in Otley. The railway then crosses the dramatic stone Arthington Viaduct over the River Wharfe.
