Coirpre Cromm mac Crimthainn (died 577)[1] was a King of Munster from the Eóganacht Glendamnach sept of the ruling Eoganachta dynasty.
King lists contained in the Laud Synchronisms, the Book of Leinster and the saga Senchas Fagbála Caisil (The Story of the Finding of Cashel) also mention him.
In 572, he fought the Battle of Feimin (plain between Cashel and Clonmel, County Tipperary), and defeated Colmán Bec mac Diarmata (died 585) and many of the men of Meath were slain.
[6] A poem on the origin of the name of Loch Cenn gives the following information about this battle:[7] His sons were Feidlimid mac Coirpri Chruimm, a possible king of Munster, and Áed Fland Cathrach, who was ancestor of the later kings from the Glendamnach line.
[8] His widow Cumman married Feidlimid mac Tigernaig, also King of Munster.
