West Riding of Yorkshire

The West Riding of Yorkshire is one of three historic subdivisions of Yorkshire, England. From 1889 to 1974 the riding was an administrative county named County of York, West Riding. The lieutenancy at that time included the city of York and as such was named "West Riding of the County of York and the County of the City of York". The riding ceased to be used for administrative purposes in 1974, when England's local government was reformed.

Contemporary local government boundaries in Yorkshire largely do not follow those of the riding. West Yorkshire lies entirely within the former area of the riding, as does most of South Yorkshire and the south-west of North Yorkshire. The riding also included areas that are now part of Cumbria, Lancashire, Greater Manchester, and the East Riding of Yorkshire.
