Robert Burnet, Lord Crimond was a Scottish advocate and judge.
He was the fourth son of Alexander Burnett of Leys by his wife Katherine, daughter of Alexander Gordon of Lesmoir, and younger brother of Sir Thomas Burnett, 1st Baronet.
Crimond studied for seven years in France, and was admitted a Scottish advocate on 20 February 1617.
His career at the Bar was so successful, that in 1628 he acquired Banachtie and Mill of Bourtie from William Seton of Meldrum, and, in 1634, Crimond, in Aberdeenshire, which afterwards became his residence. He refused to subscribe to the Solemn League and Covenant, and as a consequence spent several years in exile in Paris from 1637. In that year he wrote to his brother-in-law, Archibald Johnston of Warristoun, protesting against the injustice of the sentence passed upon he bishop Thomas Sydserf.
After his return he was urged by Oliver Cromwell to act as a judge, but declined, and lived in retirement on his estate at Crimond until the restoration of King Charles II of England.
He was nominated a Senator of the College of Justice on 19 January 1661 and took his seat in the Court of Session under the judicial title Lord Crimond on 1 June, an office he enjoyed scarcely three months before dying at Edinburgh on 24 August. Upon his death, Alexander Brodie of Brodie paid the following diary tribute to his memory:.."27 August 1661.
I heard that the good Mr Robert Burnet, Crimond, was removed by death. "The righteous are taken away and perishing,none considering or laying it to hart, that they are taken away from the euel to come".
