The St. Alexander Nevsky Military Cathedral of Tiflis (Georgian: ტფილისის სამხედრო ტაძარი, tp'ilisis samkhedro tadzari; Russian: Тифлисский Александро-Невский военный собор, Tiflisskiy Aleksandro-Nevskiy voyenny sobor) was an Orthodox Christian cathedral in downtown Tiflis (now Tbilisi), Georgia, constructed during the Imperial Russian rule in 1871-1872 and 1889–1897 and demolished by the Soviet authorities in 1930. The novel design of the cathedral became a standard for the emerging Neo-Byzantine style well before the cathedral was completed.
