Tupik (Тупик) is a village (selo) and administrative center of Tungiro-Olyokminsky District of Zabaykalsky Krai, Russia, located on the Olyokma River, north of Mogocha. Population: 1,041 (2002 Census); 1,069 (1989 Census).
Tupik was founded in 1911 as a result of an unsuccessful attempt of paving the road to Yakutsk. The project was frozen over because of the outbreak of World War I, which is how the village got its name (literally meaning cul-de-sac).
During the war, many POWs were sent here. In April 1919, a partisan group of internationalists, mainly Hungarians, was exterminated by the Japanese expeditionary corps and ataman Grigory Semyonov's troops (the Jewish regiment).
