Slieve Carr, also known as Slieve Cor or Corslieve (Irish: Corrshliabh, meaning 'conspicuous mountain'), is a mountain with a height of 721 metres (2,365 ft) in County Mayo, Ireland. It is part of the Nephin Range and is beside Nephin Beg. On the summit is a burial cairn known as Laghtdauhybaun, from Leacht Dáithí Bháin, 'burial monument of white Dáithí'. This is believed to refer to Dathí, a king of Connacht in the 5th century.
