Slovenia participated in the Eurovision Song Contest 1999 with the song "For a Thousand Years" written by Sašo Fajon and Primož Peterca. The song was performed by Darja Švajger, who had previously represented Slovenia in the Eurovision Song Contest in 1995 where she placed seventh with the song "Prisluhni mi". Slovenian broadcaster Radiotelevizija Slovenija organised the national final EMA 1999 in order to select the Slovenian entry for the 1999 contest in Jerusalem, Israel. 17 entries competed in the national final where "Se tisoc let" performed by Darja Švajger was selected as the winner following the combination of votes from a four-member jury panel and a public televote. The song was later translated from Slovene to English for the Eurovision Song Contest and was titled "For a Thousand Years".

The Eurovision Song Contest 1999 was the 44th edition of the Eurovision Song Contest, held on 29 May 1999 at the International Convention Centre in Jerusalem, Israel. Organised by the European Broadcasting Union (EBU) and host broadcaster Israel Broadcasting Authority (IBA), the contest was held in the country following its victory at the 1998 contest with the song "Diva" by Dana International, and was presented by Dafna Dekel, Yigal Ravid and Sigal Shachmon.
