The Nagnatae (ÃÂñóýìÃÂñù) or Magnatae (ÃÂñóýìÃÂñù) were a people of ancient Ireland, recorded in Ptolemy's 2nd century Geography as living in northern Connacht. O'Rahilly suggests a connection between the Nagnatae and the Fir ÃÂl nÃÂcmacht, a people of early Connacht, assuming a degree of corruption in the transmission of both names. For the town in their territory see Nagnata.
