John Dickson, Lord Hartree or Hartrie (July 1600 – 1653) was a 17th-century Scottish judge and Senator of the College of Justice and a Member of Parliament.
In 1633 he acquired the Hartree estate 1 mile south of Biggar, previously controlled by the Brown family, but under the feudal ownership of the Earl of Traquair.
[1][2] He was Depute Clerk Register to Sir Alexander Gibson, Lord Durie.
Not until 1649 did he become an advocate and this seems to have been a contrivance to allow his election as a Senator of the College of Justice to replace his wife's uncle, George Haliburton, Lord Fodderance.
One daughter, Elizabeth Dickson (1641-1669) married Sir George Mackenzie of Rosehaugh.
