Luccreth moccu Chíara (floruit c. 665 AD) was a poet from County Kerry, Ireland who wrote in archaic Old Irish. Moccu is an archaic form marking affiliation to an ancestral population group or gens, in this case the Cíarraige. James Carney identifies the poet in genealogies of the Cíarraige as the last of six sons of a certain Áine, a descendant of Mug Airt, also known as Cíar, son of the legendary Ulaid hero Fergus mac Róich and supposed founder of the Cíarraige. The genealogies add that Luccreth had no children, and that "His dwelling-place faces the church of Cluain on the south".
