Slovenia in the Eurovision Song Contest 1999

For the Eurovision Song Contest 1999, Slovenia entered "Se Tesoc Let", performed by Darja Švajger. The song would be translated into English as "For A Thousand Years" before the Contest was held.

On February 26, the Slovene final was held at the RTVSLO studios in Ljubljana, and was hosted by Mojca Mavec. There were 17 songs in the final, and the winner was decided by experts - one of whom was Marc Roberts, who had represented Ireland in 1997 - and televoting, with the televotes only counting for a third of the overall result. The favourite amongst the televoters was "Zakaj".

It was the second time that Darja Švajger represented Slovenia, having represented her country in the 1995 Contest. She also entered the heats for the 1993, 1997 and 1998 Contests. Nuša Derenda would go on to represent the country in 2001. In Jerusalem, Darja received 50 points, finishing 11th.
