Greece in the Eurovision Song Contest 2004

Greece was represented at the Eurovision Song Contest 2004 with the song "Shake It", composed by Nikos Terzis, with lyrics by Nektarios Tyrakis, and performed by Sakis Rouvas. The Greek participating broadcaster, Hellenic Broadcasting Corporation (ERT), internally selected its entry for the contest. Prior to Rouvas' selection, the broadcaster had organised a public selection process entitled Eurostar, consisting of live semi-final heats, leading to a three-participant national final to select its entrant. While the event did take place and Apostolos Psichramis was selected as the Greek entrant, the song selection portion did not materialize after the Rouvas announcement and Psichramis instead joined Rouvas as a backing vocalist.

To promote the entry, a music video for the song was released and Rouvas made appearances at events in Greece, Finland, Lithuania, Malta, France, Spain, and the United Kingdom. Greece was drawn to appear 10th in the semi-final, which was held on 12 May. There, the nation placed third with 238 points and qualified for the final, held three days later. At the final, Greece placed third with 252 points, tying its best contest placement to this point.
