Ludwig Karl August von Hagemeister (; Leontij Andrianovic Gagemejster; ) was a Russian naval officer who held the rank of Captain of the 1st rank in the Imperial Russian Navy. He was a maritime explorer of Alaska and the Pacific Ocean, and served briefly in 1817-1818 as the second Chief Manager of the Russian-American Company. Career in the Navy Hagemeister was born to an ethnic Baltic German family in the Russian Empire. He began his service in the Russian naval forces in 1795 as a volunteer midshipman.
