Máel Muad mac Brain, commonly anglicised Molloy, was King of Munster, first possibly from 959 or alternatively 963 to around 970, when he may have been deposed by Mathgamain mac Cennétig of the Dál gCais, and then again from 976, following his putting to death of the latter, until his own death in the Battle of Belach Lechta against Mathgamain's brother Brian Bóruma in 978.
