Mykolas Sleževičius (21 February 1882 – 11 November 1939) was a Lithuanian lawyer, political and cultural figure, and journalist. One of the most influential figures in inter-war Lithuania, he served as the prime minister of Lithuania on three occasions. Taking the helm of the government at a difficult time in 1918 and again in 1919, Sleževičius has been credited with preparing Lithuania for the fights to come and for laying the foundations of the fledgling state.
