Tyrconnell (Irish: Tír Chonaill, meaning 'Land of Conall'), also spelled Tirconnell and Tirconaill, was a kingdom of Gaelic Ireland.

The kingdom represented the core homeland of the Cenél Conaill people of the Northern Uí Néill and although they ruled, there were smaller groups of other Gaels in the area.

In the 12th century the kingdom of Ailech split into two sovereign territories and Cenél Conaill became Tír Chonaill under the Ó Domhnaill (O'Donnell) clan.

[2] The Hereditary Seneschal of Tyrconnell (currently vested in a living O'Donnell, who was already ennobled as a Knight of Malta, and who inherited the Seneschalship from his father), survives under the auspices of the Hereditary Great Seneschal or Lord High Steward of Ireland, currently Charles Chetwynd-Talbot, 22nd Earl of Shrewsbury, senior direct descendant of George Carpenter, 2nd Earl of Tyrconnell (of the 4th creation), and senior kin of Richard Talbot, Duke of Tyrconnel.

Indeed, the Christian religion was of particular significance to the O'Donnell rulers of Tyrconnell, as their kinsman St. Colm Cille (also known as St. Columba), born at Conwal and Leck, was regarded as one of the three patron saints of Ireland.
