Alexander Seton, 1st Earl of Dunfermline (1555–1622) was a Scottish lawyer, judge and politician. He served as Lord President of the Court of Session from 1598 to 1604, Lord Chancellor of Scotland from 1604 to 1622 and as a Lord High Commissioner to the Parliament of Scotland.

The Lord President of the Court of Session and Lord Justice General is the most senior judge in Scotland, the head of the judiciary, and the presiding judge of the College of Justice, the Court of Session, and the High Court of Justiciary. The Lord President holds the title of Lord Justice General of Scotland and the head of the High Court of Justiciary ex officio, as the two offices were combined in 1836. The Lord President has authority over any court established under Scots law, except for the Supreme Court of the United Kingdom and the Court of the Lord Lyon.
