Civic Alliance of Serbia (Serbian: Грађански савез Србије, Građanski savez Srbije) was a social liberal party in Serbia. Known widely by its three-letter acronym in Serbian, GSS was founded and registered in 1992. It came into existence through the merger between an entity called the Republican Club and the Reformist Party (Serbian successor to Ante Marković's SFR Yugoslavia-wide Union of Reform Forces party). In 1996 Žarko Korać left GSS with a group of dissidents and formed the Social Democratic Union (SDU). However, GSS merged into Liberal Democratic Party on April 7, 2007.
