Bulgarian National Television (BNT), a member organisation of the European Broadcasting Union (EBU), have been responsible for the selection process of their participants, since their debut in 2007.

Their next appearance in the contest was in 2021, where Denislava and Martin achieved the country's worst result to date; 16th place out of 19 participating entries with the song "Voice of Love".

Bulgaria returned for the 2014 edition in Malta, earning their best ever result in a Eurovision competition when Krisia, Hasan and Ibrahim placed second performing "Planet of the Children".

In June 2016 BNT selected their artist for the Junior Eurovision Song Contest 2016 in Valletta, Lidia Ganeva.

After initially confirming their participation for the 2017 contest in Georgia,[4] Bulgaria withdrew their application due to restructuring within the broadcaster[5] and did not appear on the final list of countries released by the EBU on 9 August 2017.

In 2015, the online broadcasts featured commentary in English by junioreurovision.tv editor Luke Fisher and 2011 Bulgarian Junior Eurovision Song Contest entrant Ivan Ivanov.
