Social Democratic Party of Bosnia and Herzegovina

The Social Democratic Party of Bosnia and Herzegovina (Bosnian: Socijaldemokratska partija Bosne i Hercegovine, abbr. SDP BiH) is a social democratic political party in Bosnia and Herzegovina. It is considered the successor of the League of Communists of Bosnia and Herzegovina, the Bosnian branch of the former League of Communists of Yugoslavia. Initially established as a multi-ethnic party, the SDP BiH has since the early 2000s experienced a decline in support among Croats and Serbs, and its voter base has become predominantly Bosniak.

In the period after the Bosnian War, the SDP BiH emerged as the leading non-nationalist party in Bosnia and Herzegovina. The party achieved significant success in the 2000 general election, forming a ruling coalition led by SDP member Božidar Matić. However, in the 2002 elections, the party suffered major losses and was pushed into the opposition. The SDP BiH returned to power following the 2010 general election, but once again lost influence in the 2014 elections. The party entered the government of the Sarajevo Canton after the 2018 election, and in 2020 formed the Troika alliance. Following the 2022 general election, the SDP BiH became part of the ruling coalition at the national level as well.

The SDP BiH remains the main center-left party in the country and continues to advocate for a unified, multi-ethnic Bosnia and Herzegovina based on social justice and European integration. It is a member of the Party of European Socialists, Progressive Alliance, and the Socialist International.
