Social Democratic Party of Albania

The PSD was formed in March 1991 by former members of the Party of Labour of Albania who embraced social democracy,^[4] and was admitted into Socialist International at its XIX congress in 1992.^[5] The party placed third in the 1992 parliamentary election, winning seven seats.^[6] It won only 1.52% and no seats in the 1996 election, but contested the 1997 election in an alliance with the Socialist Party, with the PSD winning nine seats.^[7]

In the 2001 elections the party was reduced to four seats competing independently. The 2005 elections saw the party increase its representation back to seven seats. For the 2009 election it was part of the "Unification for Changes" alliance with the Socialist Party, but received just 1.8% of the national vote and lost all its seats. In the 2017 election it returned to parliament with one seat. The 2021 election saw the party win three seats which it retained at the 2025 election.

The party's political base is in the north of the country, specifically Shkodër and Kukës counties. In the 2025 parliamentary election the party won 16% of the vote in Shkodër and 13% in Kukës, its two strongest performances. Social Democrat Edmond Ndou holds the office of Chairman of the Shkodër County Council.
