Greece participated in the Eurovision Song Contest 2007 with the song "Yassou Maria", written by Alex Papaconstantinou, Marcus Englöf and Markus Sepehrmanesh. The song was performed by Sarbel. To select their entry for the 2007 contest, which took place in Helsinki, Finland, Greek national television broadcaster Hellenic Broadcasting Corporation (ERT) organised the national final Eurovision 2007 which took place on 28 February 2007. The event saw three acts—Sarbel, Tamta and Christos Dantis—compete to be the Greek representative.

The Eurovision Song Contest 2007 was the 52nd edition of the Eurovision Song Contest. It took place in Helsinki, Finland, following the country's victory at the 2006 contest with the song "Hard Rock Hallelujah" by Lordi. Organised by the European Broadcasting Union (EBU) and host broadcaster Yleisradio (YLE), the contest was held at the Hartwall Areena, and consisted of a semi-final on 10 May, and a final on 12 May 2007. The two live shows were presented by Finnish television presenter Jaana Pelkonen and musician and TV-host Mikko Leppilampi. In addition, Krisse Salminen acted as guest host in the green room, and reported from the crowds at the Senate Square.
