Lorne (or Lorn; Scottish Gaelic: Latharna) is an ancient district in the west of Scotland, now part of the Argyll and Bute council area.
The district may have given its name to the traditional Scottish breakfast dish Lorne sausage.
Lorne bordered (what was then a smaller) Argyll to the south, Lochaber to the north and Breadalbane to the east.
The Firth of Lorn separates Mull from islands off the Lorne coastline.
Oban is the capital of the ancient district of Lorne. Once labelled the "Charing Cross of the Highlands" because of the range of steamer connections with the islands and Argyll coast, Oban is still a busy port for ferries, cruise liners, fishing boats and pleasure craft.
The district may have taken its name from Loarn mac Eirc, a brother of Fergus Mór Mac Earca who, around the year 500 AD became ruler of the Scottish Kingdom of Dál Riata. Loarn created his own dynasty in the new kingdom, in the district of Argyll to which he gave his name.
