Cúán úa Lothcháin was an Irish poet from Tethba, now in County Meath.
Born in the region of Tethba - part of the kingdom of Mide - Cúán acted as bard and propagandist for High King Máel Sechnaill mac Domnaill (died 1022).
The Annals of the Four Masters give his obit as- "M1024.4 Cuan Ua Lothchain, chief poet of Ireland, and a learned historian, was slain in Teathbha, and the party who killed him became putrid in one hour; and this was a poet's miracle."
The Annals of Loch Cé give his obit as- "LC1024.4 Cuan Ua Lochain, i.e. the chief poet of Erinn, was slain by the men of Tethfa.
God performed a ‘poet's miracle,’ manifestly, on the party that killed him, for they died an evil death, and their bodies were not buried until wolves and birds preyed upon them."
