Caomhánach (Irish: Irish pronunciation: ['kiːwaːnˠəx]; Caoṁánaċ in Gaelic type) is an Irish-language surname first assumed by Domhnall Caomhánach, eldest son of the 12th-century Diarmait Mac Murchada, king of Leinster (now Leinster, Ireland). A considerable number of anglicised variations of Caomhánach exist; some of the most common are Kavanagh, Cavanagh, Kavanaugh and Cavanaugh.
