Slovenia was represented at the Eurovision Song Contest 2018 with the song "Hvala, ne!", written by Lea Sirk and Tomy DeClerque, and performed by Lea Sirk herself.

Entries were selected to advance from the semi-final based on a public televote and a jury panel. Eight entries qualified to compete in the final where "Hvala, ne!" performed by Lea Sirk was selected as the winner following the combination of votes from six thematical juries and a public televote.

Slovenia was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 10 May 2018. Performing during the show in position 17, "Hvala, ne!" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 12 May. It was later revealed that Slovenia placed eighth out of the 18 participating countries in the semi-final with 132 points. In the final, Slovenia performed in position 3 and placed twenty-second out of the 26 participating countries with 64 points.
