The prime minister of Lithuania (, , colloquially also referred to as the premier ) is the head of government of Lithuania. The prime minister is appointed by the president with the assent of the Lithuanian parliament, the Seimas. The modern office of prime minister was established in 1990, when Lithuania declared its independence, although the official title was "Chairperson of the Council of Ministers" until 25 November 1992.

Historically, the title of prime minister was also used between 1918 and 1940. This was during the original Republic of Lithuania, which lasted from the collapse of the Russian Empire until the country's annexation by the Soviet Union.

Following the ultimatum in June 1940, the forces of Soviet Union entered Lithuania, prompting President Antanas Smetona to flee the country. Antanas Merkys, who assumed the position of acting president in accordance with the constitution, soon announced he had taken over the Presidency on a permanent basis and appointed Justas Paleckis, favored by the Soviet authorities, as the Prime Minister ahead of the "people's government". Merkys soon resigned, allowing Paleckis to assume the post of acting president as well. The presidency of Merkys is not recognized as legitimate in modern Lithuania and Paleckis is not listed as an interwar Prime Minister in government sources.
