Muintir Murchada was the name of an Irish territory which derived its name from the ruling dynasty, who were in turn a branch of the Uí Briúin. The name was derived from Murchadh mac Maenach, King of Uí Briúin Seóla, who died 891.
They are first recorded as a lineage in 1061 and by 1238 the term denoted the territory. It came under the control of the Uí Briúin about the 11th century, its original rulers taking the surname Ó Flaithbheartaigh (O'Flaherty). They were expelled by the Ua Conchobhair Kings of Connacht to Iar Connacht where they are still to be found.
Muintir Murchada appears to have comprised the following parishes: Killursa, Kilkilvery, Killeany, Kilcoona, Cargin, Killower, Cummer. It also is thought to have included parts of Belclare, Donaghpatrick, Corofin, Tuam, Kilbennan and Killererin.
