Archibald Campbell (died 1744) was a clergyman of the Scottish Episcopal Church who served as Bishop of Aberdeen.
He was a student of the church fathers and the author of a book The Doctrine of the Middle State between Death and the Resurrection (1721) in defence of prayer for the dead.
He assisted in the preparation of the Usagers Communion Office of 1718, and was the author of the first hymn extant written by an Episcopalian.
When Brett engineered a reunion with the non-usager nonjurors in the early 1730s, Campbell, Laurence, and Deacon stood apart and constituted the extreme usager party.
The Orthodox British Church, as it became known, had congregations in London, Shrewsbury and Manchester, the latter lasting into the first decade of the nineteenth century.
