The North Riding of Yorkshire was one of the three historic subdivisions (ridings) of the English county of Yorkshire, alongside the East and West Ridings. From the Restoration it was used as a Lieutenancy area. The three ridings were treated as three counties for many purposes, such as having separate Quarter Sessions. An administrative county was created with a county council in 1889 under the Local Government Act 1888 on the historic boundaries. In 1974 both the administrative county and the Lieutenancy of the North Riding of Yorkshire were abolished, being succeeded in most of the Riding by the new non-metropolitan county of North Yorkshire.

The highest point in the North Riding was Mickle Fell at 788 metres (2585 ft).

During the English Civil War, the North Riding predominantly supported the royalist cause, while other areas of Yorkshire tended to support the parliamentarians.

The County of York, North Riding administrative county was formed in 1889. In 1894 it was divided into municipal boroughs, urban districts and rural districts under the Local Government Act 1894. Middlesbrough had already been incorporated as a municipal borough in 1853 and formed a county borough, exempt from county council control, from 1889. Richmond and Scarborough had been incorporated as municipal boroughs in 1835, with Thornaby-on-Tees added in 1892.

Yorkshire (/ˈjɔːkʃə/) is a historic county of Northern England and the largest in the United Kingdom. Due to its great size in comparison to other English counties, functions have been increasingly undertaken over time by its subdivisions, which have also been subject to periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographical territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the military, and also features in the titles of current areas of civil administration, such as North Yorkshire, South Yorkshire, West Yorkshire and East Riding of Yorkshire. The county's name is commonly abbreviated as Yorks.

Within the borders of the historic county of Yorkshire are areas which are widely considered to be among the greenest in England, due to the vast stretches of unspoiled countryside in the Yorkshire Dales and North York Moors and to the open aspect of some of the major cities. Yorkshire has sometimes been nicknamed God's Own County. The emblem of Yorkshire is the white rose of the English royal House of York, and the most commonly used flag representative of Yorkshire is the White Rose on a dark blue background, which after years of use, was recognised by the Flag Institute on 29 July 2008.Yorkshire Day, held on 1 August, is a celebration of the general culture of Yorkshire, ranging from its history to its own dialect.
