The Seimas of the Lithuanian Republic (Lithuanian: Lietuvos Respublikos Seimas), or simply the Seimas (/ˈsməs/ SAY-məs; Lithuanian: [ˈsɛɪˑmɐs]), is the unicameral legislative body of the Republic of Lithuania.

The Seimas constitutes the legislative branch of government in Lithuania, enacting laws and amendments to the Constitution, passing the budget, confirming the Prime Minister and the Government and controlling their activities. The Seimas traces its origins to the Seimas of the Grand Duchy of Lithuania and the Sejm of the Polish-Lithuanian Commonwealth, as well as the Seimas of inter-war Lithuania. The first Seimas after the restoration of independence of Lithuania convened in 1992.

Its 141 members are elected for a four-year term, with 71 elected in individual constituencies, and 70 elected in a nationwide vote based on open list proportional representation. A party must receive at least 5%, and a multi-party union at least 7%, of the national vote to qualify for the proportional representation seats. Following the elections in 2024, the Social Democratic Party of Lithuania is the largest party in the Seimas, signing an agreement to form a coalition government with the Union of Democrats "For Lithuania" and the Dawn of Nemunas.
