Saint Gregory the Illuminator Church, commonly referred to as the Armenian Church of Baku (, "Bak’vi haykakan yekeghetsi"; ), is a former Armenian Apostolic church near Fountains Square in central Baku, Azerbaijan. Completed in 1869 it was one of the two Armenian churches in Baku to survive the Soviet anti-religious campaign and the Karabakh conflict and the 1990 pogrom and expulsion of Baku Armenians when it was looted. It is the only standing Armenian monument in Baku.
