Clan Campbell (Scottish Gaelic: Na Caimbeulaich [na ˈkʰaɪmbəl̪ˠɪç]) is a Highland Scottish clan. Historically one of the largest and most powerful of the Highland clans, their lands were in Argyll and the chief of the clan became the Earl and later Duke of Argyll.

In traditional genealogies of the Clan Campbell, its origins are placed amongst the ancient Britons of Strathclyde. However, the earliest Campbell in written records is Gillespie who is recorded in 1263. Early grants to Gillespie and his relations were almost all in east-central Scotland. However, the family's connection with Argyll came some generations before when a Campbell married the heiress of the O'Duines and she brought with her the Lordship of Lochow. Because of this the early clan name was Clan O'Duine and this was later supplanted by the style Clan Diarmid. This name came from a fancied connection to Diarmid the Boar, a great hero from early Celtic mythology.

The original seat of the Clan Campbell was either Innis Chonnell Castle on Loch Awe or Caisteal na Nigheann Ruaidh on Loch Avich. The clan's power soon spread throughout Argyll, however at first the Campbells were under the domination of the Lords of Lorne, chiefs of Clan MacDougall. The MacDougalls killed the Campbell chief Cailean Mór (Colin Campbell) in 1296. (See: Battle of Red Ford). All of the subsequent chiefs of Clan Campbell have taken MacCailean Mór as their Gaelic patronymic.
