Terringzean Castle, also Taringzean, pronounced 'Tringan', is a Category B listed castle ruin lying above the River Lugar and the Terringzean Holm in the policies of Dumfries House, Parish of Cumnock, Scotland. The name Craufordstone or Craufurdstoun, has also been used, echoing that it and these lands originally belonged to the Crawfords, as did Leifnorris or Lochnorris Castle which stood on the site of what is now Dumfries House.
