David MacGill, McGill or Makgill, Lord Cranston Riddell (1532–1595) was a 16th-century Scottish judge and Senator of the College of Justice and Lord Advocate of Scotland from 1582 to 1595.
[citation needed][4] His eldest brother was James MacGill, Lord Rankeillor.
[5] In June 1582 he was elected a Senator of the College of Justice and took the title Lord Cranston Riddell.
His place on the Senate was taken by his eldest son, also David MacGill in 1597, who continued the title Lord Cranston Riddell, causing some confusion between father and son.
[3] His second son, Sir James MacGill was also a Senator and also known as Lord Cranston Riddell.
