Leabhar Donn is a 15th-century genealogical manuscript, seemingly written and compiled on the border of counties Sligo and Leitrim. It was written in two periods: 1432–1441 and 1476–1482.
David Sellar, who was the Lord Lyon King of Arms in Scotland, concluded that it dates from the mid 15th century.
