Clan MacDougall is a Highland Scottish clan.

The Clan MacDougall takes its name from Dougall, the son of Somerled who was killed at the Battle of Renfrew in 1164. After Somerled's death, Dougall held most of Argyll as well as the islands of Mull, Lismore, Jura, Tiree, Coll and others.

The Celtic first name Dougall, or Dugald is derived from the Gaelic dubh-gall, which means black stranger. Dougall's royal descent was acknowledged by the king of Norway and Dougall himself was styled as 'King of the South Isles and Lord of Lorne'. One of Dougall's sons seems to have been Óspakr-Hákon, a man installed as King of the Isles by Hákon Hákonarson, King of Norway in 1230. A certain son of Dougall was Duncan, who was in turn the father of Ewan. Duncan and Ewan built many castles to defend their territory. These included Dunstaffnage Castle, Dunollie Castle and Duntrune Castle on the main land. Whilst on the islands they built Aros Castle, Cairnburgh Castle, Dunchonnel Castle and Coeffin Castle. Dunollie Castle is believed to have been fortified since the 6th century and became the seat of the chief of Clan MacDougall. Duncan also built Ardchattan Priory and it was here that the MacDougall chiefs were buried until 1737.
