Gianna Terzi (Greek: Γιάννα Τερζή; born 1 December 1980) is a Greek singer and songwriter. She represented Greece in the Eurovision Song Contest 2018 with the song "Oniro mou".
Terzi was born on 1 December 1980 in Thessaloniki. She is the daughter of Greek singer Paschalis Terzis. At age 20, she moved to Athens to pursue a music career, releasing the album Gyrna to kleidi in 2006 through Cobalt Music. She then signed to Minos EMI and released the album Ase me na taxidepso in 2008 along with a single of the same name. Terzi later moved to the United States and worked as a talent scout for Interscope Records.
Terzi was selected as one of the twenty shortlisted artists for the Ellinikós Telikós 2018 with the song "Oniro mou" on 27 October 2017, representing Panik Records. Later, on 8 November, she became one of the five acts to be selected to move on to the televised final.
Following the disqualification of two of the five acts for not having a "Greek sound", "Óniro mou" entered the top three. On 15 February 2018, it was reported that the record labels for the two other competing artists refused to pay a € 20,000 fee to the Greek broadcaster Hellenic Broadcasting Corporation (ERT) and were disqualified from the competition, leaving "Óneiró mou" as the only song remaining and the default Greek entry. She failed to qualify to the final of the Eurovision Song Contest.
