John Morison, 6th Baron of Bognie and Mountblairy, (1757 – 12 February 1835) was a British politician who sat in the House of Commons as the Member of Parliament (MP) for Banffshire, Scotland, between 1827 and 1832. He was the second son of Alexander Morison, 4th Baron of Bognie, and Catharine Duff.
During the 1780s and 1790s, John was occupied as a merchant in Riga, before acquiring the lands of Auchintoul (Aberchirder) in 1799. John married Jane Fraser, daughter of Alexander Fraser (8th of Strichen). He was known primarily as John Morison of Auchintoul, though he did succeed his elder brother as 6th Baron of Bognie and Mountblairy for the final four months of his life.
