An Leabhar Muimhneach, also known as The Book of Munster, is an Irish genealogical manuscript.
An Leabhar Muimhneach is preserved in a number of 18th century manuscripts, the most complete being the work of the scribe Richard Tipper of Dublin, 1716âÂÂ1717. Based on works compiled by Domhnall àDuinnÃÂn and Tadhg mac Dáire Mheic Bhruaideadha, in the early 17th century. A translation was made by Eugene O'Keeffe in 1703, and a complete scholarly edition by Tadhg àDonnchadha in 1940. This work is not to be confused with the Red Book of Munster () by Murchadh àCuindlis.
