Lissoughter or Lissoughter Hill is a prominent hill between the Twelve Bens and Maumturks mountain ranges, at the southern entrance to the Inagh Valley, in the Connemara National Park of County Galway, Ireland. With a height of 401 metres (1,316 ft), it does not qualify to be an Arderin or a Vandeleur-Lynam, however, its prominence of 336 metres (1,102 ft) ranks it as a Marilyn.
