Sir George Mackenzie of Rosehaugh (1636–1691) was a Scottish lawyer, essayist, and legal writer who served as Lord Advocate. He was an active figure in the legal and literary spheres of seventeenth-century Scotland, producing both professional legal texts and personal essays.
In addition to his professional and literary pursuits, Mackenzie acquired the historical nickname 'Bloody Mackenzie.' This moniker arose from his controversial activities and prosecutions during his tenure as Lord Advocate, marking a complex legacy that spans both legal scholarship and political notoriety.
