    • Muiredach mac Murchada (died 760) was a King of Leinster from the Uí Dú n l a i n ge branch of the Laigin. He was the son of Murchad mac Brain Mut ( d i e d 7 2 7), a previous king. He ruled from 738 to 760.

      The Laigin had suffered a crushing defeat at the Battle of Áth Senaig ( B a l l y shannon, County Kildare) in 738 at the hands of the High King Áed A l l á n m a c Fergaile (died 743) of the Cenél nEógain. Muiredach maintained g o o d r e l ations the High King of Ireland, Domnall Midi (died 763) of the C l a n n C h olmáin. Muiredach's son Bran Ardchenn mac Muiredaig (died 795) m a r r i e d Domnall Midi's daughter Eithne. In 759 Domnall led a host of the L a i g i n a s far as Mag Muirtheimne, near Dundalk.

      Muiredach was ancestor of the Uí Muiredaig sept of the Uí Dunlainge wit h t h e i r r oyal seat at Maistiu (Mullaghmast) in south Kildare, in the te rr i t o r y known as Iarthair Liphi (western Liffey). His son Bran Ardchenn m a c M u i r edaig (died 795) was also king of Leinster.
