Cyprus participated in the Eurovision Song Contest 2009. CyBC announced that Cyprus's 2009 Eurovision entry would be selected through a national final where the general public will be the one to decide the winner via 100% televoting. The national final was held on February 7, 2009.

Cyprus has participated in the Eurovision Song Contest twenty-six times since its first entry in 1981. Its best placing was fifth, which it achieved three times: in 1982 with the song "Mono I Agapi" performed by Anna Vissi, in 1997 with "Mana Mou" performed by Hara and Andreas Constantinou, and 2004 with "Stronger Every Minute" performed by Lisa Andreas. Cyprus's least successful result was in 1986 when it placed last in 1986 with the song "Tora Zo" by Elpida, receiving only three points in total. However, its worst finish in terms of points received was when it placed second to last in 1999 with "Tha'nai Erotas" by Marlain Angelidou, receiving only two.

The Cypriot national broadcaster, Cyprus Broadcasting Corporation (CyBC) broadcasts the event in Cyprus each year and organizes the selection process for its entry. Selection processes have varied over the years from full national finals such as in 2004, 2006, and 2008, where the public chooses both the song and performer, to internal selections such as in 2005 and 2007 where the artist and sometimes song also is chosen by CyBC. For 2009, CyBC chose to hold a national final as it had the previous year.
