The 27th (Inniskilling) Regiment of Foot was an Irish infantry regiment of the British Army, formed in 1689. Under the Childers Reforms it amalgamated with the 108th (Madras Infantry) Regiment of Foot to form the Royal Inniskilling Fusiliers in 1881.

The regiment was raised as local militia at Enniskillen by Colonel Zachariah Tiffin as Zacharaiah Tiffin's Regiment of Foot in June 1689, to fight against James II in the Williamite War in Ireland. The regiment served successfully, most notably at the Battle of Newtownbutler in July 1689, and it gained a place on the English establishment in 1690 as a regular infantry regiment. As such it then fought at the Battle of the Boyne in July 1690, at the Battle of Aughrim in July 1691 and at the Siege of Limerick in August 1691. A contingent from the regiment took part in the Siege of Namur in August 1695 during the Nine Years' War.

The regiment was deployed to the West Indies in late 1739 but returned in December 1740. It formed part of the Government army sent to defeat the Jacobite rising of 1745, participating in the Battle of Falkirk in January 1746 and in the Battle of Culloden in April 1746. At this period they were commonly known as Blakeney's Regiment after the colonel-in-chief. In 1751, the regiment was formally titled the 27th (Enniskillen) Regiment of Foot.

In 1756 the regiment departed for Canada and fought against the French at the Battle of Carillon in July 1758 and the Battle of Ticonderoga in July 1759 during the Seven Years' War. It then took part in the Invasion of Martinique in January 1762 and the capture of Grenada in February 1762. It also took part in the Battle of Havana in June 1762 during the Anglo-Spanish War: the regiment suffered heavy losses and was evacuated to New York. In August 1767 the regiment returned to Ireland.
