The Bulgarian participant broadcaster in the contest is the Bulgarian National Television (BNT).

However, on three of the five occasions that they have reached the final, they have finished in the top five: placing fifth with "Water" by Elitsa and Stoyan in, fourth with "If Love Was a Crime" by Poli Genova in , and second with "Beautiful Mess" by Kristian Kostov in 2017.

Participation
The Bulgarian National Television (BNT) is a full member of the European Broadcasting Union (EBU) since 1 January 1993, thus eligible to participate in the Eurovision Song Contest since then. It has participated in the contest representing Bulgaria since its in 2005. Before becoming a member of the EBU, earlier contests had often been broadcast on BNT.

The first participant in the contest with a Bulgarian origin is Nora Nova, a jazz and a pop singer who left Bulgaria for political reasons in 1959 and later represented in 1964.

1993–2003
BNT had planned to debut at the Eurovision Song Contest in 1993, 1996, and 2003; the latter year the broadcaster was unable to take part after the EBU decided that too many countries would be relegated from participation in 2003 if the country took part.

2005–2010
Bulgaria ultimately debuted at the contest in, with the song "Lorraine" performed by the jazz-inspired band Kaffe. Receiving only 49 points, they placed 19th in the semi-final and failed to qualify to the final. They were succeeded by "Let Me Cry" by Mariana Popova, however it also failed to qualify for the final, coming 17th with 36 points in the semi-final.

Bulgaria's first qualification for the final came in with "Water" by Elitsa Todorova and Stoyan Yankoulov. This was the first Bulgarian-language song to compete in the contest, placing 6th in the semi-final with 146 points. Todorova and Yankulov repeated their song in the final and received 157 points, placing 5th in a field of 24.

In previous years, if a country placed in the top 10 countries in the final they automatically qualified to the final of the next contest. Had this rule remained for the 2008 contest, Bulgaria would have directly qualified for the final. However, a change in rules due to the large intake of countries participating in the contest meant that only five countries, the host country and the "Big Four" countries, would automatically qualify to the final. As such, Bulgaria was obliged to compete in one of the two semi-finals of the 2008 contest.

At the 2008 contest, Bulgaria were represented by "DJ, Take Me Away" by Deep Zone and Balthazar. They, however, could not repeat Todorova and Yankulov's result and received only 56 points, placing 11th of 19 competing in the second semi-final, thereby failing to qualify Bulgaria for the final.

Bulgaria competed in the 2009 contest in Russia, with a two-phase national selection process beginning in October 2008. The winner was Krassimir Avramov with his song "Illusion". It failed to qualify for the final, coming 16th out of 18 participants in the first semi-final.

In October 2009, BNT announced that Miroslav Kostadinov would represent Bulgaria at the 2010 contest in Oslo, Norway, with the song "Angel si ti". It was the first song since 2007 to be sung in Bulgarian. However, for the third consecutive year, Bulgaria's entry failed to qualify for the final, coming 15th out of 17 participants in the second semi-final.

2011–2018
In 2011, Bulgaria was represented by Poli Genova, and the country's entry was sung in Bulgarian for the second consecutive year. Her song was called "Na inat", and missed out on a place for the final after coming 12th in the Semi-final 2, making 2011 the fourth year in a row that Bulgaria didn't reach the final. In that year she competed with 18 more singers in the final of "EuroBGvision" (where by means of SMS voting the TV audience selects who will represent Bulgaria in the Eurovision Song Contest). This was her fourth time in which she took part in the "EuroBGvision" and her first win.

Sofi Marinova represented Bulgaria in the 2012 contest in Baku with "Love Unlimited". Her song was mainly in Bulgarian, but it also contains the phrase "I love you" in 12 other languages, including Turkish, Greek, Spanish, French, and Serbian. Bulgaria's entry tied with Norway for 10th place in its semi-final; however, the tie broke in favor of Norway because it received points from more countries, making 2012 the fifth year in a row that Bulgaria didn't qualify.

In 2013, Elitsa Todorova and Stoyan Yankoulov were chosen through an internal selection to represent Bulgaria for a second time. Their song "Samo shampioni" placed sixth in the second semi-final's televoting results, but 17th place (last) in the jury's results. The duo placed twelfth, with 45 points, thereby failing to qualify Bulgaria for the final for the sixth consecutive year.

On 18 December 2014, BNT confirmed via their official Eurovision Twitter account that they would not take part in the 2015 contest.

On 15 September 2015, it was announced that BNT sent a preliminary application in order to compete in the 2016 contest, and the effective participation was further confirmed on 26 November 2015. Poli Genova was selected to represent Bulgaria for the second time, having previously done so in 2011. With "If Love Was a Crime", Poli performed twelfth at the second semi-final on 12 May 2016, and qualified for the final by finishing in 5th place with 220 points. In the final on 14 May 2016, she performed eighth and placed 4th with 307 points.
