The Republican League (Lithuanian: Respublikonų lyga, Polish: Liga Republikańska), originally known as the Lithuanian Polish People's Party (Lithuanian: Lietuvos lenkų liaudies partija, Polish: Polska Partia Ludowa) was a centre-left political party in Lithuania which represented the interests of the Polish minority. It was established as a left-wing competitor to the Electoral Action of Poles in Lithuania. The party performed poorly and was disbanded in 2017.

The party was registered on 23 September 2002 and founded by the initiative of Ryszard Maciejkianiec, a former Member of the Seimas from the Union of Poles in Lithuania (later a member of the Lithuanian Social Democratic Union) and the editor-in-chief of Nasz Czas.^[3] The first chairwoman of the party was Polish community activist, journalist Antonina Poltawiec.^[4]

Immediately after its registration, the party began cooperation with the European Free Alliance and was admitted to the alliance as a full member in 2004.^[2]

The party was founded with the intent of providing an alternative to the Electoral Action of Poles in Lithuania, which at the time had become dominant in the Polish-majority areas of Lithuania, and was highly promoted by Nasz Czas.^[3]

In the 2002 local elections, Maciejkianiec was elected to the municipal council of Vilnius District Municipality, where he remained until 2007.^[5] In the 2004 parliamentary election, it ran candidates in nine constituencies with Polish populations, but won no seats.^[6]

In 2010, the party was renamed to the Republican League and abandoned its status as a regionalist Polish minority party, though it continued to strive for the integration of Lithuanian Poles and other national communities into the country's economic, cultural and social political life. Jan Szybakowski was elected as its new chairman.^[7] The reorganization did not turn the party's fortunes around and the party was liquidated on 2017 after failing to provide a list of members.^[8]

According to its program approved in 2006, the party

is a regional political party of the Vilnius Region, which unites the centre-left citizens of the Republic of Lithuania in its ranks, is based on Christian traditions, and seeks to strengthen democracy, social equality, solidarity, the development of the economy and local self-government in Lithuania. The LLLP will support the establishment of the rule of law and civil society, the consolidation of democratic principles, the defence of human rights and freedom, and will strive to ensure the free development of the traditions, language and culture of the national communities living in Lithuania. The LLLP will take special care of the development of the Vilnius region, feeling responsible for its future, appreciating the diversity of cultures and peoples and the traditions of tolerance and coexistence that have been preserved in this region for centuries, since the times of the Grand Duchy of Lithuania. The LLLP advocates the creation of a European Union of free peoples, based on the principle of support and solidarity with the other peoples of the world, which itself is based on state citizenship and regional identity.^[1]

The party proposed replacing the existing administrative divisions of Lithuania with five regions - Žemaitija, Suvalkija, Dzūkija, Aukštaitija and the Vilnius Region. It supported Lithuania's integration into NATO and the European Union and was socially conservative.
