Colmán of Dromore was a 6th-century Irish saint and bishop who served as the first leader of the monastic community at Dromore. Born in Dalriada, he was baptized by his uncle, a bishop of the same name. After receiving early training at the monastery of Nendrum, he traveled to study the Scriptures at the school of Emly. He later returned to Mahee Island to assist his former teacher, where he instructed various students, including the future Saint Finnian of Moville.
