Archibald Campbell, 9th Earl of Argyll, Scottish peer (d. 1685)

Archibald Campbell, 9th Earl of Argyll (26 February 1629 – 30 June 1685) was a Scottish peer and soldier.

The hereditary chief of Clan Campbell, and a prominent figure in Scottish politics, he was a Royalist supporter during the latter stages of the Scottish Civil War and its aftermath. During the period of the Cromwellian Protectorate he was involved in several Royalist uprisings and was for a time imprisoned.

Despite his previous loyalty, after the Restoration of Charles II, Argyll fell under suspicion due to his hereditary judicial powers in the Highlands and his strong Presbyterian religious sympathies. Condemned to death in 1681 on a highly dubious charge of treason and libel, he escaped from prison and fled into exile, where he began associating with Whig opponents of the Stuart regime. Following the accession of Charles' brother to the throne as James II in 1685, Argyll returned to Scotland in an attempt to depose James, organised in parallel with the Monmouth Rebellion. Argyll's Rising failed, and Argyll was captured and beheaded.
