Máel Muire ("servant of Mary") mac Céilechair (died 1106) was an Irish cleric of the monastery of Clonmacnoise, County Offaly, and one of the principal scribes of the manuscript Lebor na hUidre.
He came from a prominent clerical family with links to Clonmacnoise going back six centuries.
Máel Muire was one of the three scribes who worked on the manuscript Lebor na hUidre, the earliest and one of the most important collections of early Irish literature.
He wrote his name on the manuscript in two marginal probationes pennae (pen tests), and comparison of the handwriting identifies him as one of the two scribes who wrote the original manuscript, which was later amended by a third hand.
[1] The Annals of the Four Masters record his death in 1106 in a Viking raid on Clonmacnoise.
