The Diocese of Meath is a nineteenth century history of the Roman Catholic Diocese of Meath from mediæval to nineteenth century times, written by one of the Diocese's priests, Dean Cogan.
Published in two volumes in 1862 and 1867, it remains a basic reference book for anyone interested in the history of Christianity in Ireland, because it relied for information on three sources of information no longer available to modern historians; folklore and folk memories from people in the 1850s and 1860s that covered such time periods as the Penal Laws and the Irish Potato Famine; information from the Meath diocese's own archives, which were subsequently lost during a move of the Bishop's cathedral seat from Navan to Mullingar; and information from Ireland's Public Records Office, all of whose contents were destroyed when the IRA blew up the PRO in 1922.
