The Ten-Day War (Slovene: desetdnevna vojna) or the Slovenian Independence War (slovenska osamosvojitvena vojna), also the Weekend War (vikend-vojna) was a civil war in Yugoslavia that followed the Slovenian declaration of independence on 25 June 1991. It was fought between the Slovenian Territorial Defence (Slovene: Teritorialna obramba Republike Slovenije) and the Yugoslav People's Army (YPA) in 1991, after Slovenia declared its independence. It lasted from 27 June 1991 until 7 July 1991, when the Brijuni Accords were signed.

Following the death of Yugoslav president Josip Broz Tito in 1980, underlying political, ethnic, religious, and economic tensions within Yugoslavia surfaced. In 1989 Slobodan Milošević, Chairman of the Central Committee of the League of Communists of Serbia since 1986, became president of Serbia, the largest and most populous of the six Yugoslav republics. In April 1990, Slovenia held its first democratic multi-party elections, won by the DEMOS coalition.
