Jonas Variakojis (May 5, 1892 near Rinkuškiai, Lithuania – October 31, 1963 in St. Charles, Illinois, United States) was a Lithuanian army officer. Variakojis was studying law at the University of St. Petersburg when he was mobilized into the Russian army and sent to the Austrian front during World War I. In December 1918 he returned to Lithuania and joined the newly organized Lithuanian army, preparing to defend Lithuania against the Red Army during the Lithuanian–Soviet War. Variakojis was ordered to organize defense of Panevėžys district. On February 7, 1919, he led the first Lithuanian battles against the Soviets near Kėdainiai. The Soviet advance was stopped, preventing them from capturing Kaunas, the temporary capital of Lithuania.
