Georgy Lvovich Brusilov (Russian: Гео́ргий Льво́вич Бруси́лов) or Hryhoriy Brusylov (May 19, 1884 in Nikolayev, Russian Empire (now Mykolaiv, Ukraine) – 1914?) was a Russian naval officer of the Imperial Russian Navy and an Arctic explorer. His father, Lev Brusilov, was also a naval officer.
In 1912 Brusilov led a maritime expedition which was intended to explore and map a route from the Atlantic Ocean to the Pacific via a northeast passage, also called the Northern Sea Route. His expedition disappeared almost without a trace, and despite searches its ultimate fate was unknown until 2010.
During 1910–1911, Georgy Brusilov participated in the Arctic Ocean Hydrographic Expedition of the Russian Hydrographic Service on icebreakers Taymyr and Vaygach, visiting the Chukchi Sea and East Siberian Sea.
In 1912, Brusilov commanded the Brusilov Expedition using the brig St. Anna, which was intended to travel from the Atlantic Ocean to the Pacific by the Northern Sea Route. One of the members of the expedition was a 22-year-old nurse, Yerminia Zhdanko, daughter of a general who had been a hero in the Russo-Japanese War.
