Stefania Liberakakis (; born 17 December 2002), known simply as Stefania, is a Greek-Dutch singer, voice actress and YouTuber. She is a former member of the girl group Kisses, which represented the Netherlands in the Junior Eurovision Song Contest 2016. In 2020, she was internally selected to represent Greece in the Eurovision Song Contest 2020 with the song "Supergirl", but this edition of the contest was later cancelled due to the COVID-19 pandemic. The Greek broadcaster ERT decided that Liberakakis would represent Greece in the 2021 contest instead, where she finished in tenth place.
