The Yorkshire Mounted Brigade was a formation of Britain's part-time Territorial Force organised in 1908.

Mobilised on the outbreak of World War I, its regiments had been posted away by 1915 so it was broken up.

From April 1893 the Army List began showing the Yeomanry Cavalry regiments grouped into brigades for collective training.
