Yorkshire Day is celebrated on 1 August to promote the historic English county of Yorkshire. It was celebrated in 1975, by the Yorkshire Ridings Society, initially in Beverley, as "protest movement against the Local Government re-organisation of 1974", The date alludes to the Battle of Minden, and also the anniversary of the emancipation of slaves in the British Empire in 1834, for which a Yorkshire MP, William Wilberforce, had campaigned.

The day was already celebrated by The Light Infantry, successors to the King's Own Yorkshire Light Infantry, as Minden Day. Together with five other infantry regiments of the British Army, a rose is permitted to be worn in the headdress. In the case of the Light Infantry, the rose is white.

Amongst the celebrations there is a Civic gathering of Lord Mayors, Mayors, and other Civic Heads from across the country, convened by the Yorkshire Society, which has been held in :

Saltburn and Saddleworth have also played host.

Similar events have been promoted by the Friends of Real Lancashire (27 November, since 1996) and the Huntingdonshire Society (25 April, since 2002) to promote their causes.

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.
