The Democratic Party of Kosovo (Albanian: Partia Demokratike e Kosovës, PDK) is a major political party in Kosovo. It was founded in October 1999 after the Kosovo War by political figures associated with the Kosovo Liberation Army (KLA), and was originally known as the Party for the Democratic Progress of Kosovo before adopting its current name in 2000. The party was led for most of its early history by Hashim Thaçi, who later served as prime minister and President of Kosovo, and it became one of the dominant parties of Kosovo's first two decades after the war.

The PDK began as a party with a social-democratic and post-war state-building profile, but gradually moved toward the centre-right. At its 2013 convention it formally presented itself as a centre-right party, while later joining liberal European and international party organisations, including the ALDE Party and Liberal International. The party has generally supported Kosovo's independence, Euro-Atlantic integration, cooperation with the United States, market-oriented economic policies, and the strengthening of Kosovo's security institutions.

PDK led the government of Kosovo from 2007 to 2014 under Hashim Thaçi and remained in government after the 2014 election through a coalition with the Democratic League of Kosovo (LDK). It was also part of the 2017 PANA coalition government led by Ramush Haradinaj. Since the 2019 election, the party has generally been in opposition to governments led or dominated by Vetëvendosje. As of 2026, it is led by Bedri Hamza, who replaced Memli Krasniqi as party chairman on 17 November 2025.

In the June 2026 parliamentary election, PDK finished second with 19.44% of the vote and 22 seats in the Assembly of the Republic of Kosovo, remaining the largest opposition party. Its parliamentary group is led by Arian Tahiri.

The Democratic Party of Kosovo was founded on 10 October 1999, shortly after the end of the Kosovo War and the establishment of international administration under UNMIK. It was initially registered as the Party for the Democratic Progress of Kosovo (Albanian: Partia për Progres Demokratik e Kosovës), and was renamed the Democratic Party of Kosovo on 21 May 2000.

The party emerged from the political wing of the demilitarised Kosovo Liberation Army, and many of its founders and early leaders had been involved in the KLA or in the People's Movement of Kosovo, an underground nationalist organisation that had supported armed resistance to Serbian rule. This background distinguished the PDK from the Democratic League of Kosovo (LDK), which had developed from the peaceful resistance movement led by Ibrahim Rugova.

Hashim Thaçi, one of the most prominent KLA political representatives during the war and the head of Kosovo's provisional post-war political structure, became the party's first leader. Other important figures in the party's early history included Kadri Veseli, Jakup Krasniqi, Fatmir Limaj, Xhavit Haliti, Bajram Rexhepi and Ramë Buja. The party initially presented itself as a modern democratic and social-democratic force committed to Kosovo's independence, reconstruction and institution-building.

In the first years after the war, the PDK competed with the LDK for leadership of Kosovo's Albanian-majority political scene. The LDK remained the largest party in the first post-war elections, but the PDK quickly established itself as the main opposition party and the principal representative of the former KLA political current.
