Joker Out is a Slovenian boy band formed in 2016. They describe their sound as "shagadelic rock and roll".
Their formation came in the aftermath of the breakup of the band Apokalipsa, where three of the members were part of. They released their first single "Kot srce ki kri poganja" in 2016 and have since released 9 singles and 2 studio albums. In 2017, they won the 4th season of Špil league.
On 8 December 2022, RTV SLO announced that the group would represent Slovenia at the Eurovision Song Contest 2023 in Liverpool, marking the country's first internal selection since Hannah Mancini in 2013. Their song Carpe Diem finished in 21st place.
Frontman Bojan Cvjetićanin was one of the members of the Slovenian jury for the 2021 contest in Rotterdam, and co-wrote his Eurovision successor Raiven's entry for the 2024 contest.
