Carrickmore (from Irish: an Charraig Mhór, meaning "the big rock") is a town in County Tyrone, Northern Ireland. It lies in the heart of the county on a raised site colloquially called "The Rock"; between Cookstown, Dungannon and Omagh. It is situated in the historic barony of Omagh East and the civil parish of Termonmaguirk. It had a population of 612 in the 2001 Census. In the 2011 Census 2,330 people lived in the Termon Ward, which covers the Carrickmore and Creggan areas.
The area is steeped in history and there are many tales and legends connected with St. Colmcille and the town, including the saint's well, chair and bed which are still in existence. A wide range of historic monuments can be found in the Carrickmore area, including cairns, stone circles, standing stones and raths.
The Dean Brian Maguirc College, a second level education school, is named after Dean Brian McGurk who was Vicar-General to St Oliver Plunkett during the Penal Times and died in Armagh Gaol aged 91.
Carrickmore holds the annual Tyrone County Commemoration of the 1916 Easter Rising and a remembrance ceremony for all republicans killed in The Troubles since 1969.
Two historical figures from the Clan na Gael and Irish Republican Brotherhood hailed from the Carrickmore area: Joseph McGarrity and Patrick McCartan, who helped fund the 1916 Easter Rising.
