Social Democratic Party of Serbia

A centre-left political party in Serbia, orientated towards the principles of social democracy.

The Social Democratic Party of Serbia (SDPS) was formed on 5 October 2009 by Rasim Ljajić, the long-time leader of Sandžak Democratic Party. Ljajić has been the president of SDPS since its formation. In late 2013 SDPS had joined in coalition with the Sandžak Democratic Party, forming a political union. Rasim Ljajić was elected as the SDPS-SDP's first head. Despite taking part with the Democratic Party-led Choice for a Better Life alliance in the 2012 Serbian parliamentary election, SDPS has aligned itself with the Serbian Progressive Party (SNS) after the election. Since then, it has contested every election on the SNS electoral list.

Its headquarters is at Dečanska 1/III in Belgrade. In 2015, it was reported that SDPS had 44,658 members. In 2020, SDPS had 48,623 members.

In June 2018 the party was admitted in the Socialist International as observer member, and promoted to full member in 2024.
