Bulgaria was represented at the Eurovision Song Contest 2018 with the song "Bones" written by Borislav Milanov, Joacim Bo Persson, Trey Campbell and Dag Lundberg. The song was performed by the group Equinox. The Bulgarian broadcaster Bulgarian National Television (BNT) organised the internal selection process BG Song 2018 in order to select the Bulgarian entry for the 2018 contest in Lisbon, Portugal. On 12 March 2018, BNT announced that Equinox had been selected to compete with "Bones", which was presented to the public on the same day.
