The 18th Mounted Brigade, previously known as the 2/1st Yorkshire Mounted Brigade, was a 2nd Line yeomanry brigade of the British Army during the First World War. In July 1916 it was converted to a cyclist formation as 11th Cyclist Brigade and in November 1916 was redesignated as 7th Cyclist Brigade. It was still in existence, in Ireland, at the end of the war.
