Greece in the Eurovision Song Contest 2023

Greece was represented at the Eurovision Song Contest 2023 with the song "What They Say" written and performed by Victor Vernicos. The Greek participating broadcaster, Hellenic Broadcasting Corporation (ERT), internally selected its entry for the contest. Vernicos was announced as the artist on 30 January 2023, while the song was presented to the public on 12 March. The entry selection process was subject to a legal challenge by second-place candidate Melissa Mantzoukis; however, Vernicos' participation was ultimately allowed to continue.

To promote "What They Say" as the Greek entry, a music video for the song was created as well as an acoustic version. Vernicos subsequently attended a meet-and-greet and gave interviews to foreign press. Greece was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 11 May 2023. Performing during the show in position eight, "What They Say" placed 13th in the semi-final with 14 points, failing to qualify for the contest's final. This marked Greece's third non-qualification and also its worst result to this point in terms of points received in a semi-final.
