Joost Klein

Joost Klein (Dutch pronunciation: [joːst klɛin]; born 10 November 1997), also known mononymously as Joost, is a Dutch musician, rapper, singer, and former YouTuber. Mainly a hip hop artist, his songs and performances often include influences of electronic music, such as drum and bass, hardstyle, and gabber. He has released seven studio albums, two of which reached the top ten of the Dutch Album Top 100. He has amassed four chart entries on the Dutch Top 40, and is best known for "Wachtmuziek" (2022), "Europapa" (2024), "Luchtballon" (2024) and his collaborations with German rapper Ski Aggu and comedian Otto Waalkes on "Friesenjung" (2023), Finnish rapper Käärijä on "Trafik!" (2024), and Estonian rapper Tommy Cash on "United by Music" (2025).

"Europapa" was selected to represent the Netherlands in the Eurovision Song Contest 2024 and subsequently became Klein's first song to top both the Dutch Top 40 and Single Top 100. Having qualified in second place from the second semi-final, he was scheduled to perform fifth in the final, but was disqualified from the competition due to allegations of misconduct. These were investigated by Swedish prosecutors, who dropped the case in August 2024 after concluding that they could not prove any criminal conduct.
