Muirgheas mac Pháidín Ó Maolconaire, Gaelic-Irish scribe, died 1543.
Muirgheas was a native of Cluain Plocáin (now Ballymulconry), parish of Kiltrustan, County Roscommon. It lies close to an inlet of the river Shannon, north of Strokestown.
Ó Maolconaire wrote the Book of Fenagh in 1516/17, at Fenagh Abbey, County Leitrim. He prepared an abbreviated version in 1535, now [[BL Cotton Vespasian MS E II]]
Muirgheas was responsible for writing the vellum manuscript known as Leabhar gabhála, or Leabhar Bhaile Uí Mhaoilchonaire do sgríobh Muirghios mac Paídín Uí Mhaoilchonaire as Liobhar na hUidhre. An incomplete version survives as RIA MS D iv 3
He has sometimes been confused with his great-grandson, Muiris mac Torna Ó Maolconaire (died 1645).
