Greece participated in the Eurovision Song Contest 2018. The Greek national broadcaster Hellenic Broadcasting Corporation (ERT) announced that they will use a national final in order to find the Greek representative in Lisbon, after two consecutive years of internal selection. This decision was later reversed when all but one of the competing finalists' record labels were unable to provide a guarantee of the €20,000 fee requested by ERT, and thus "Oneiro mou" sung by Gianna Terzi was internally selected.

Prior to the 2017 contest, Greece had participated in the Eurovision Song Contest thirty-seven times since their debut in 1974. The nation has won the contest on one occasion in 2005 with the song "My Number One" performed by Helena Paparizou. Following the introduction of semi-finals for the 2004, Greece has managed to thus far qualify to the final with each of their entries. Between 2004 and 2011, the nation achieved eight consecutive top ten placements in the final. To this point, Greece in 2016 with Argo's "Utopian Land" failed to qualify from the semi-finals for the first time ever, being absent from the final for the first time since 2000. This was Greece's worst result at the contest. However, Greece returned to the final in 2017 with Demy's song "This Is Love", finishing in 19th place.

The Greek national broadcaster, Hellenic Broadcasting Corporation (ERT), broadcasts the event within Greece and organises the selection process for the nation's entry. ERT had been in charge of Greece's participation in the contest since their debut in 1974 until 2013 when the broadcaster was shut down by a government directive and replaced with the interim Dimosia Tileorasi (DT) and then later by the New Hellenic Radio, Internet and Television (NERIT) broadcaster. Following the January 2015 Greek legislative election, a draft proposal was initiated to reinstate ERT as the public Greek broadcaster. On 28 April 2015, the draft was approved and signed into law by the Hellenic Parliament, resulting in the renaming of NERIT to ERT; ERT began broadcasting once again on 11 June 2015. ERT confirmed their intentions to participate at the 2016 Eurovision Song Contest on 28 August 2015. The Greek broadcaster has used various methods to select the Greek entry in the past, such as internal selections and televised national finals to choose the performer, song or both to compete at Eurovision. Since 2010, the Greek entry has been selected via a national final that featured a competition among several artists and songs with the votes of an expert jury and a public televote deciding the Greek Eurovision entry.
