The East Yorkshire Regiment was a line infantry regiment of the British Army, first raised in 1685 as Sir William Clifton's Regiment of Foot and later renamed the 15th Regiment of Foot. It saw service for three centuries, before being amalgamated with the West Yorkshire Regiment (Prince of Wales's Own) to form the Prince of Wales's Own Regiment of Yorkshire in 1958. Subsequently, the regiment amalgamated with the Green Howards and the Duke of Wellington's Regiment (West Riding) to form the Yorkshire Regiment (14th/15th, 19th and 33rd/76th Foot) on 6 June 2006.

Raised in 1685 in Nottingham by Sir William Clifton, 3rd Baronet, the regiment was originally, like many British infantry regiments, known by the name of its current Colonel. It took part in the Battle of Killiecrankie in July 1689 and the Battle of Cromdale in April 1690 during the Jacobite rising of 1689 to 1692.

The regiment embarked for Flanders in spring 1694 for service in the Nine Years' War and took part in the capture of Huy in autumn 1694, the attack of Fort Knokke in June 1695 and the Siege of Namur in summer 1695 before returning home in 1697.

The regiment was sent to Holland in 1701 for service in the War of the Spanish Succession and fought at the siege of Kaiserswerth in 1702, the siege of Venlo later that year and the Battle of Blenheim in August 1704. It went on to fight at the Battle of Ramillies in May 1706, the Battle of Oudenarde in July 1708 and the Battle of Malplaquet in September 1709. It returned to England in 1714. It was sent to Scotland and took part in the Battle of Glen Shiel in June 1719 during Jacobite rising.
