Accession of Serbia to the European Union (EU) is on the agenda for future enlargement of the EU.

Serbia applied to join the EU in 2009 and has been a candidate for membership since 2012 (along with nine other states), while negotiations started in 2014 and are still ongoing.

History Relations between the European Union and the Federal Republic of Yugoslavia (later the State Union of Serbia and Montenegro) got a fresh start following the overthrow of Slobodan Milošević in 2000, and the EU officially declared the Balkan states potential candidates for membership following the EU-Western Balkans Summit in Thessaloniki in 2003.

On 7 November 2007, Serbia initiated a Stabilisation and Association Agreement (SAA) with the European Union. The SAA came into force on 1 September 2013. The European Commission recommended making Serbia an official candidate on 12 October 2011. The Council of the European Union also made the recommendation on 28 February 2012. Serbia received full candidate status on 1 March 2012. In December 2013, the Council of the European Union approved opening negotiations for Serbia's accession. Serbia officially applied for European Union membership on 22 December 2009 and was granted official candidate status on 1 March 2012. Negotiations on accession to the EU started on 21 January 2014.

Until 2020, Serbia had been receiving €2.9 billion of developmental aid from the Instrument for Pre-Accession Assistance, a funding mechanism for EU candidate countries.

In 2024, Serbian President Aleksandar Vučić stated that Serbia would meet all the criteria to join the European Union by 2026 or 2027, but did not promise an immediate accession in 2026, 2027, or 2028. These statements reflect his earlier ones, when he stated that Serbia would probably have to wait for six years to join the European Union, in 2030. The 2030 target was later supported by the President of the European Council, Charles Michel, during the Bled Strategic Forum, who stated that such enlargement should be ready to proceed by 2030. However, in 2025, during a meeting in Rome regarding the Western Balkans "expansion", Minister of Foreign Affairs of Italy, Antonio Tajani, with the presence of the European Commissioner for Enlargement, Marta Kos, stated that a possible entry year for the nation could be 2029 instead.

Membership talks No further progress on the opening or closing of chapters has been achieved since December 2021. Benchmarks were met for the opening of all three remaining chapters in cluster 3 (chapter 10, 16 and 19) in December 2024, but this was postponed due the opening being conditional on "substantial further progress made by Serbia, in particular in accordance with...the rule of law (chapter 23+24) and the normalisation of relations with Kosovo".

In June 2026, EU officials had discussed proposals to open Cluster 3 (Competitiveness and inclusive growth) after the Serbian parliament rolled back a series of controversial judicial reforms. The European Commission proposed to open Cluster 3, but this proposal faced opposition from several member states, most notably the Netherlands, which threatened to veto the opening of the cluster over rule of law concerns.
