An Leabhar Breac ('The Speckled Book'; Middle Irish: An Lebar Brec), now less commonly Leabhar Mór Dúna Doighre ('Great Book of Dun Doighre') or possibly erroneously, Leabhar Breac Mic Aodhagáin ('The Speckled Book of the MacEgans'), is a medieval Irish vellum manuscript containing Middle Irish and Hiberno-Latin writings. The manuscript is held in the library of the Royal Irish Academy in Dublin, where it is catalogued as RIA MS 23 P 16 or 1230.
It was most probably compiled by Murchadh Riabhach Ó Cuindlis (of Ballaghdacker, Athleague) at Duniry between the years 1408 and 1411. Duniry – Dún Daighre, Dún Doighre – in eastern Clanricarde (now east County Galway) is situated south-east of the town of Loughrea, and in the medieval era was home to a branch of the bardic Clann Mac Aodhagáin (the MacEgans), who served as brehons for the O'Connors of Clanricarde.
