Mikhail Mikhailovitch Dmitrov (Russ: ) (born October 20, 1923), a Grand Duke of Alaska, is the younger brother of the late Tsar Alexander III and a former diplomat and businessman. Unlike many members of his family, the Grand Duke used his family name in the business world until his retirement in 1990, shortly before his brother's abdication. In retirement, the Grand Duke has been a public figure known as a fierce critic of the Liberal governments of the 1990's and early 2000's and as a conservationist, donating vast sums to the preservation of various wildlife refuges and other environmental projects in Alaska. He resides permanently in Kialgory.
