The Lord Chancellor of Scotland, formally the Lord High Chancellor, was a Great Officer of State in the Kingdom of Scotland.
Holders of the office are known from 1123 onwards, but its duties were occasionally performed by an official of lower status with the title of Keeper of the Great Seal. From the 15th century, the Chancellor was normally a Bishop or a Peer.
At the Union, the Lord Keeper of the Great Seal of England became the first Lord High Chancellor of Great Britain, but the Earl of Seafield continued as Lord Chancellor of Scotland until 1708. He was re-appointed in 1713 and sat as an Extraordinary Lord of Session in that capacity until his death in 1730.
