Muirgheas mac Pháidín Ó Maolconaire, Gaelic-Irish scribe, died 1543. He 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. He also wrote 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 is sometimes confused with his great-grandson, Muiris mac Torna Ó Maolconaire (died 1645).
