Anna Vissi represented Greece in the Eurovision Song Contest 2006 with her song "Everything". The Greek national broadcaster, Ellinikí Radiofonía Tileórasi (ERT), internally selected Vissi to represent the country at the contest, which took place in Athens after Greece's win at the 2005 contest with the song "My Number One" performed by Elena Paparizou. "Everything", composed by Nikos Karvelas and written by Anna Vissi herself, was selected on March 14, 2006 at a national final by a combination of a televoting/SMS vote (60%) and expert jury (40%). At Eurovision, Vissi placed 9th, receiving 128 points.

The Eurovision Song Contest 2006 marked Greece's twenty-seventh participation in the Contest since its first entry in 1974. It won for the first time at the previous contest in 2005 with the song "My Number One" performed by Elena Paparizou, and had been placed third twice up to the Contest: in 2001 with the song "Die for You" performed by the duo Antique and in 2004 with "Shake It" performed by Sakis Rouvas. Following the introduction of semi-finals for the 2004 contest, Greece has had a top ten placing each year. Greece's least successful result was in 1998 when it placed twentieth with the song "Mia Krifi Evesthisia" by Thalassa, receiving only twelve points in total, all from Cyprus.
