Fermoy (Irish: Mainistir Fhear Maí, meaning 'monastery of the men of the plain')[8] is a town on the River Blackwater in east County Cork, Ireland.

The ringfort at Carntierna on top of Corrin hill, 2.4 km (1.5 mi) south of Fermoy, was an important Iron Age site.

At the dissolution of the monasteries during the Tudor period, the abbey and its lands passed through the following dynasties: Sir Richard Grenville, Robert Boyle and William Forward.

In 1797, when the army was looking to establish a new and permanent base, Anderson gave them the land as an inducement to locate in Fermoy.

During the Irish War of Independence the Irish Republican Army (led by the commandant of the Cork Number Two Brigade Liam Lynch)[11] launched an attack using motor vehicles against a group of off-duty King's Shropshire Light Infantry (KSLI) soldiers on 7 September 1919 as they were attending a Wesleyan Church parade in Fermoy.

The IRA killed one soldier (a private named Jones), wounded four and disarmed the rest of their weapons.

After jurors from Fermoy serving on Jones' coroner inquest refused to return a verdict describing his death as a murder, 200 soldiers from the KSLI launched an unofficial reprisal against businesses owned by the jury, looting several drapery and shoe stores.

[12] During the Irish Civil War anti treaty forces were compelled to evacuate Fermoy and burned the barracks and other buildings before retreating into surrounding hills (10 August 1922).

The town's industries also include electronics manufacturing and assembly by Sanmina-SCI Corporation, formerly Space Craft Incorporated.

[citation needed] The Blackwater river is one of the town's major attractions and is popular for its salmon and coarse fishing.

[citation needed] The Christian Brothers, the Presentation and Loreto Sisters and Jehovah's Witnesses maintain a presence in the town.
