Throughout the 20th century, Greece achieved only two top five results, finishing fifth with "Mathema solfege" by Paschalis, Marianna, Robert, and Bessy in 1977 and again fifth with "Olou tou kosmou i elpida" by Cleopatra in 1992.

The start of the 21st century saw Greece become one of the most successful countries in the contest, with ten out of thirteen top-ten results between 2001 and 2013, including third-place finishes for "Die for You" by Antique in 2001 (with 2005 winner Paparizou as lead singer), "Shake It" by Sakis Rouvas in 2004, and "Secret Combination" by Kalomira in 2008.

Since 2014, Greece has had less success, including thrice failing to qualify for the final (2016, 2018, and 2023), although the country finished in the top ten twice during this period: in 2021 with "Last Dance" by Stefania, and in 2022 with "Die Together" by Amanda Tenfjord.

Elliniki Radiofonia Tileorasi (ERT) is a full member of the European Broadcasting Union (EBU), thus eligible to participate in the Eurovision Song Contest representing Greece.

The country's debut in the contest in its 19th edition in 1974 was by ERT's predecessor Ethniko Idryma Radiofonias Tileoraseos (EIRT), and the Greek participation in the 2014 and 2015 contest was by ERT's replacement during its closure Nea Elliniki Radiofonia, Internet kai Tileorasi (NERIT).

These singers were Jimmy Makulis (1961) for Austria, Yovanna (1965) for Switzerland, and Nana Mouskouri (1963) and Vicky Leandros (1967 and 1972) for Luxembourg.

[2] Greece did not participate in 1975 for "unknown reasons" according to the EBU, but it was later discovered that it was in protest of Turkey's debut and its invasion of Cyprus in 1974.

Polina stated that it was due to political troubles in Greece at the time,[7] but she noted that a Eurovision website had learned that the real reason was that the contest was to be held the night before Orthodox Easter.

During the 1990s, Greece achieved two top-ten results with Cleopatra and Katy Garbi reaching fifth and ninth place in 1992 and 1993 respectively.

[11] Greece returned in 2001, and was represented by the Greek-Swedish duo Antique, consisting Helena Paparizou and Nikos Panagiotidis.

Rouvas' song "Shake It" was the first to compete in a contest semi-final, which had been introduced to accommodate the growing number of participating nations.

Thirty-one years after its debut, Greece won for the first time in 2005 with Helena Paparizou (appearing as a solo performer) singing "My Number One".

The victory made Greece the first country that was not a member of Big Four to win the contest without participating in a semi-final.

Greece has been one of the most successful countries in the Eurovision Song Contest in the 21st century with 12 times finishing in the top-ten[14] and 20 in total.

In 2013, ERT was shut down by a government directive and replaced with the interim Dimosia Tileorasi (DT) and later by the NERIT broadcaster.

In 2019, ERT selected internally Katerine Duska to represent Greece in Tel Aviv with the song "Better Love" finishing 21st.

[24] Greece was drawn to compete in the second semi-final and was to perform in the first position, but on 18 March, the contest was cancelled due to the COVID-19 pandemic.

[30] For 2022, ERT opened a submission period on 7 September 2021 where artists and composers were able to submit up to three songs each for consideration by the broadcaster with a 10 October 2021 deadline.

[31] 25 artists were reported to have submitted applications from a total of more than 40 entries, and a seven-member jury panel shortlisted five entrants in late October 2021.

[32] On 15 December 2021, the committee selected the Greek-Norwegian artist Amanda Tenfjord with the song "Die Together" to represent the country in Turin.
