The first Athens Pride took place in June 2005 in Klathmonos Square. Various pride events had been held in the city since the mid-1980s, but Athens Pride 2005 marked the first downtown Pride Parade, which passed outside the Hellenic Parliament in broad daylight. An estimated 500 people attended that event.

Since 2005, the Athens Pride Festival has been growing and developing, both in terms of participation and recognition and respect from Greek society, becoming an integral institution of the city and its people. Until 2016, Athens Pride took place in Klathmonos Square, while in 2017 it was organized for the first time in Syntagma Square. The transfer of the event to the most central square of the country has been a request of the community for years, due to the increase in the participation of the people as well as its symbolic importance, which brought Athens Pride in front of the Greek Parliament. It is even estimated that 150,000 people of all ages and identities participated in the 18th Athens Pride, on June 18, 2022.
