The Annals of Loch Cé (also Annals of Lough Cé) cover events, mainly in Connacht and its neighbouring regions, from 1014 to 1590. It takes its name from Lough Cé in the kingdom of Moylurg - now north County Roscommon - which was the centre of power of the Clan MacDermot. For its earliest centuries it used the Annals of Boyle.
The largest part of the Annals are attributed to members of Clan Ó Duibhgeannáin, with some emendations by the patron, Brian na Carriag MacDermot, first MacDermot of the Carrick (died 1592). The text is in Early Modern Irish, with a portion of the text in Latin.
