John Campbell (1758–1828) was a Church of Scotland minister who served as Moderator of the General Assembly in 1818.
In August 1781 he was licensed to preach as a Church of Scotland minister by the Presbytery of Glasgow.
In that capacity he may have assisted Rev Thomas Snell Jones for a year at Lady Glenorchy's Church in Edinburgh (but as a Church of Scotland minister could not officially preside as the General Assembly did not approve of this privately built chapel).
In 1806 he was chosen as Secretary of the Society in Scotland for Propagating Christian Knowledge and in 1807 was awarded an honorary Doctor of Divinity by Edinburgh University.
He lived his final years at 45 Albany Street[2] and died there on 30 August 1828 and was buried in Greyfriars Kirkyard.
