The Faddan More Psalter (Irish: Saltair an Fheadáin Mhóir) (also Irish Bog Psalter or "Faddan Mor Psalter") is an early medieval Christian psalter or text of the book of Psalms, discovered in a peat bog in July 2006, in the townland of Faddan More (Irish: Feadán Mór) in north County Tipperary, Ireland. The manuscript was probably written in about 800 in one of a number of monasteries in the area. A unique feature is that the inside of the leather cover is lined with papyrus, probably as a stiffening, an indication of the links between the Irish and Coptic churches at the time. After several years of conservation work, the psalter went on display at the National Museum of Ireland in Kildare St, Dublin in June 2011.
