The East Riding of Yorkshire Yeomanry was a unit of the British Army.
The formation of a Regiment of Imperial Yeomanry, known as the East Riding of Yorkshire Imperial Yeomanry, was approved on 15 April 1902.
It was converted to an armoured role in 1920. In 1956, it merged with two other Yorkshire yeomanry regiments to form the Queen's Own Yorkshire Yeomanry. Its lineage is continued today by the Queen's Own Yeomanry.
