The Green Party is a centre-left political party. It was founded in 1989 in Sofia as the Green Party of Bulgaria. The initiator for the establishment of the party and its long-time chairman was Alexander Karakachanov.
The Green Party was established on December 28, 1989 by Alexander Karakachanov and activists of the largest dissident movement "Ecoglastnost" under the name of The Green Party in Bulgaria and recorded in court in 1990 under the new Law on Political Parties. Right after its formation, the Green party became a part of the Union of the Democratic forces in Bulgaria (UDF), which was then a broad coalition of anti-totalitarian political parties and clubs. In the 7th Grand National Assembly the Green Party has 17 members of parliament and also is represented by two MPs in the 38th ordinary National Assembly.
A small party called Green Bulgaria merged into the Green Party in 2008 The Green Party was renamed to The Green Party - Bulgarian greens where Stoyan Dinkov was the chairman of the Political Council (2008-2009). President after the merger is Alexander Karakachanov and the vice-president is Trifon Grudev from the former "Green Bulgaria".

In 2005 the Green Party participated in the elections for the National Assembly under the "Coalition for Bulgaria" known as the "Triple Coalition". The Green Party had no elected representatives. The Green Party left the "Triple Coalition" before the end of the term due to fundamental disagreements regarding the Coalition's policy. The main reasons were the neoliberal policies and unequal extortionate swaps of state forests made by the ruling Coalition. Green Party held a number of protests against these actions of the government and submitted "The law for restoring the swapped forests and lands".
